Pull request description:

  Consistently use `ApplyArgsManOptions` for `PeerManager::Options`, and initialize `PeerManager::Options` early to avoid reading `"-blocksonly"` twice. Suggested in bitcoin#27499 (comment) and also requested in bitcoin#27499 (comment).

  No behaviour change, but the [`TestingSetup`](https://github.com/bitcoin/bitcoin/blob/e35fb7bc48d360585b80d0c7f89ac5087c1d405e/src/test/util/setup_common.cpp#L255-L256) is now also able to access `"-blocksonly"`.

Walkthrough

The pull request adds a Bitcoin-specific clang-tidy module that detects logging format strings without a trailing newline and offers a fix-it. It also adds sequence numbers to mempool entries and uses those sequences to determine whether peers can retrieve transactions. A functional test covers relay behavior after a reorganization. Other changes update logging call sites, startup options, callback delivery, and EvoDB state handling.

Estimated code review effort: 4 (Complex) | ~45 minutes

Use MSG_TX and transaction IDs in the relay test.

The MSG_WTX import prevents the test from starting. The framework’s CTransaction also has no getwtxid() method. Use the wallet’s txid for requests and rehash() for the received transaction.

     CInv,
-    MSG_WTX,
+    MSG_TX,
     msg_getdata,

If bitcoin::LogPrintfCheck stops reporting bad format strings, bitcoin-tidy-tests can still pass. Compare the diagnostics with expected results for the bad calls, and check that valid and NOLINT calls produce none.

Invalidate cached results when the plugin changes.

clang-tidy-cache does not hash the plugin contents. If a check changes without changing its configuration, CI can reuse an old result and miss new diagnostics in unchanged files. Include the plugin version in the cache key or isolate the cache by plugin contents.

Final validation — Phase 1 + Phase 2

Verified acd9047 against the source and current CI: the sequence-field addition changes mempool memory accounting, and the unadapted mempool-limit fixture now fails, so changes are required. The separate TSan failure reports a pre-existing lock-order cycle rather than a newly introduced ordering; ASan tests and multiprocess tests/lint remain pending. This was a static review with CI-log inspection; no local builds or tests were run, and the supplied base drift neither duplicates nor conflicts with these changes.

These findings are from an automated code review (PastaClaw). How to work through them:
- Verify each finding against the code; fix only what is real, as narrowly as the finding.
- If a finding is wrong, decline it on its thread in one or two sentences; the bot answers once and stops.
- To defer one, link a tracking issue on its thread (or reply asking the bot to file one).
- Suggestions are optional: fix them forward in a later PR rather than pushing another round just for them.
- Address every current finding in one push: self-review the full diff first, and don't push piecemeal.
- Keep the PR's scope; don't grow it to satisfy hardening suggestions.
- Carried items were raised in an earlier round: read the thread first, and don't re-fix what you already fixed, declined or deferred there. Disputed and deferred items are already handled and are not listed.

  Adding entry_sequence increases the entry overhead used by CTxMemPool::DynamicMemoryUsage(), whose calculation includes memusage::MallocUsage(sizeof(CTxMemPoolEntry) + 12 * sizeof(void*)). Dash's mempool_limit.py fills a 5 MB pool with fixed-size transactions and assumes that maxmempool minus serialized transaction bytes remains below 100,000. The changed overhead alters eviction and breaks that assumption: linux64-test fails all three attempts, with the final traceback at mempool_limit.py:127 reporting `AssertionError: 100000 <= 136750`, before testing immediate package eviction (https://github.com/dashpay/dash/actions/runs/42778022529/job/129703924808). The corresponding develop Linux job passes mempool_limit.py with the same compiler configuration; its only fixture change is an unrelated incrementalrelayfee assertion. Retain the sequence field and adapt the fixture to establish the required capacity and eviction conditions explicitly, rather than relying on this fixed relationship between serialized bytes and memory usage.
Out-of-scope follow-up suggestions (1)

These are valid observations, but they are outside this PR's scope and should be handled in separate issues or author/maintainer-requested PRs rather than blocking this review.

  • Resolve the pre-existing networking/mempool lock-order cycle — linux64_tsan-test fails during feature_llmq_chainlocks.py with a cycle involving the block-inventory mutex, transaction-inventory mutex, mempool mutex, and connection-manager node mutex. The reported relationships already exist in the base: SendMessages acquires inventory locks before mempool lookups, block invalidation invokes masternode-list notifications while holding the mempool mutex, and UpdatedBlockTip acquires the block-inventory mutex inside ForEachNode. The new sequence snapshot exposes an existing ordering rather than introducing the cycle.
    • Follow-up: Open a separate locking-fix issue or PR using the sanitizer report from job 129706153166 to remove the existing cycle and validate the fix with feature_llmq_chainlocks.py under TSan.

Resolved (re-reviewed at 711a08e0): The fixture now subtracts getmempoolinfo()["usage"] from maxmempool, so its capacity assertion accounts for the larger CTxMemPoolEntry memory usage introduced by entry_sequence.

BACKPORT NOTE:
lint-logs.py is gone and the bitcoin-unterminated-logprintf clang-tidy check that replaces it knows nothing about /* Continued */. Unlike the linter it also sees headers and judges the format string itself, so it flags 22 Dash log calls whose newline comes from an argument or from a later call. Mark those NOLINT, as bitcoin#28237 does for CommitTransaction, and remove the now meaningless markers from the remaining calls.

ci/test/06_script_b.sh hunk is adopted for Dash runs of clang-tidy from ci/dash/lint-tidy.sh.
Without the plugin loaded the bitcoin-* checks in src/.clang-tidy match nothing, and with lint-logs.py removed unterminated log strings are not checked at all.

  Demo of integrating the [bitcoin-tidy](https://github.com/theuni/bitcoin-tidy-plugin), [clang-tidy plugin](https://clang.llvm.org/extra/clang-tidy/) written by theuni into our tidy CI job.

  The plugin currently has a single check, `bitcoin-unterminated-logprintf`. This would replace our current Python driven, `git-grep`-based, `.cpp` file only, lint-logs linter.

…e mempool lock

ConnectBlock and DisconnectBlock fire the signal while ActivateBestChain holds cs_main and the mempool lock, and CMNAuth's handler iterates the nodes, so m_nodes_mutex is taken under mempool.cs.
Together with SendMessages (m_block_inv_mutex -> m_tx_inventory_mutex -> mempool.cs) and PeerManagerImpl::UpdatedBlockTip (m_nodes_mutex -> m_block_inv_mutex) that closes a lock-order cycle. bitcoin#27675 takes mempool.cs on every inventory pass, which makes ThreadSanitizer report it.

1e9684f mempool_entry: add mempool entry sequence number (Anthony Towns)

Pull request description:

  This PR replaces the `m_recently_announced_invs` bloom filter with a simple sequence number tracking the mempool state when we last considered sending an INV message to a node. This saves 33kB per peer (or more if we raise the rate at which we relay transactions over the network, in which case we would need to increase the size of the bloom filter proportionally).

  The philosophy here (compare with bitcoin#18861 and bitcoin#19109) is that we consider the rate limiting on INV messages to only be about saving bandwidth and not protecting privacy, and therefore after you receive an INV message, it's immediately fair game to request any transaction that was in the mempool at the time the INV message was sent. We likewise consider the BIP 133 feefilter and BIP 37 bloom filters to be bandwidth optimisations here, and treat transactions as requestable if they would have been announced without those filters. Given that philosophy, tracking the timestamp of the last INV message and comparing that against the mempool entry time allows removal of each of `m_recently_announced_invs`, `m_last_mempool_req` and `UNCONDITIONAL_RELAY_DELAY` and associated logic.

  There should never be a need to pass a format string that is not a compile-time string literal, so disallow it in `WalletLogPrintf()` to avoid accidentally introducing it.

Revalidate peers against the current list.

If a reorganization reverses an operator-key change before this event runs, the queued diff can still disconnect a peer using the restored key. CDSNotificationInterface forwards the old diff to CMNAuth, which compares it with the peer’s current key. Revalidate the peer against the current list before disconnecting it.

Re-review — Final validation — Phase 1 + Phase 2

The backport changes are otherwise consistent with the reviewed upstream adaptations, but the new deferred masternode-list notification introduces an unaccounted dependency cycle. The required Lint / Run linters check fails on this head with that cycle, causing downstream test jobs to be skipped.

These findings are from an automated code review (PastaClaw). How to work through them:
- Verify each finding against the code; fix only what is real, as narrowly as the finding.
- If a finding is wrong, decline it on its thread in one or two sentences; the bot answers once and stops.
- To defer one, link a tracking issue on its thread (or reply asking the bot to file one).
- Suggestions are optional: fix them forward in a later PR rather than pushing another round just for them.
- Address every current finding in one push: self-review the full diff first, and don't push piecemeal.
- Keep the PR's scope; don't grow it to satisfy hardening suggestions.
- Carried items were raised in an earlier round: read the thread first, and don't re-fix what you already fixed, declined or deferred there. Disputed and deferred items are already handled and are not listed.
