fix: reconcile interactions between the merged stability batch and record it in the changelog

[aviggiano]

Problem

The 25 stability/simplification PRs #1163–#1188 were validated individually and then merged back to back into main, with conflict resolutions replayed from a combined integration branch (#1190). Their combination fails CI in five places, and main is red until this lands. None is a product regression: four are tests or lint that one PR's change invalidated for another PR's test, and one is an error code a test pinned before #1188 changed it deliberately.

Change

One commit per interaction, each named after the PR it pairs with:

• fix(runtime): stop host artifact gates rejecting valid campaign output #1176 + refactor(runtime): delete host re-implementations of registry artifact gates #1178: the unscoped-prose gate test from fix(runtime): stop host artifact gates rejecting valid campaign output #1176 still called verifyRuntimeRequiredArtifactsForAttempt with three arguments; refactor(runtime): delete host re-implementations of registry artifact gates #1178 made the sealed attempt authority required. Pass it.
• fix(runtime): resume keeps agent auth config and a no-op attach no longer rewrites run state #1177 + fix(runtime): agent adapters never hang or reroute on telemetry and environment quirks #1173: fix(runtime): agent adapters never hang or reroute on telemetry and environment quirks #1173 made generated adapters import the runtime module when they load. fix(runtime): resume keeps agent auth config and a no-op attach no longer rewrites run state #1177's Node-run continuation test copies the Codex adapter into a project, where the relative fallback resolves to a missing path (ERR_MODULE_NOT_FOUND). The test now points the adapter at this build for that one load.
• fix(runtime): make run synchronization single-writer, idempotent, bounded and non-fatal for observers #1180 + fix(runtime): attempt and usage ledgers never block run synchronization #1186: fix(runtime): make run synchronization single-writer, idempotent, bounded and non-fatal for observers #1180's "status keeps reporting runner health when run-state synchronization fails" test forced the failure with a torn usage.jsonl; after fix(runtime): attempt and usage ledgers never block run synchronization #1186 that is only a WORKFLOW_ACCOUNTING_FAILED warning. The test now forces a real sync failure by hard-linking events.jsonl, which the journal append refuses.
• fix(runtime): resume keeps agent auth config and a no-op attach no longer rewrites run state #1177 + fix: failed launches are recorded and reported, and topology validation cannot reject compiler output #1185: resume.ts's messages interpolate value.workflow_run_id; fix: failed launches are recorded and reported, and topology validation cannot reject compiler output #1185's early return in resumeRun changed the inferred callback type to string | undefined, which the diff-limited strict lint rejects. Fall back to the run ID.
• ci: validate every package on PRs, stop cancelling main runs, and add a global complexity ceiling #1184: ci: validate every package on PRs, stop cancelling main runs, and add a global complexity ceiling #1184 converted CLI test headers to async (t) =>, so two over-budget tests count as changed lines under the diff-limited size rules. Their later phases move, unchanged, into helpers the tests call in order.
• fix: a validator rebuild no longer strands in-flight runs (validator build becomes provenance) #1188: report --require-verified now reports the artifact gate's JSON_SCHEMA_VIOLATION (as fix: a validator rebuild no longer strands in-flight runs (validator build becomes provenance) #1188 intended and its own tests pin) instead of ARTIFACT_SCHEMA_INVALID; two CLI tests expected the old code. This is visible in that command's error text.
• Changelog: the batch's entries, which each PR moved out of CHANGELOG.md to avoid 25 conflicting insertions at the same line, are recorded here in their original sections. The ci: validate every package on PRs, stop cancelling main runs, and add a global complexity ceiling #1184 entry describes its final form.

Verification

The tree of this branch is byte-identical to the combined integration branch with these fixes. On that tree: the affected runtime and CLI tests pass, pnpm -w build, pnpm -w lint, format:check, size, the dependency-advisory check, and the diff-limited strict lint (lint:strict:ci) over all 180 changed files pass. This PR's CI is the first full run of every lane on the merged result.

Risk / compatibility

Only resume.ts and the report error code change behaviour. replay.ts and fork.ts interpolate workflow_run_id the same way; they pass lint only because they are outside the diff, so an explicit return type on submitSmithersContinuation would be the durable fix (not done here).

Summary

This PR reconciles tests and CLI output with changes already merged in the stability batch, and records the batch in the changelog.

• Updates the resume message fallback and two verified-report diagnostic expectations.
• Preserves oversized CLI tests by moving later phases into helpers.
• Updates runtime test fixtures for sealed attempt authority, journal failures, and generated-adapter loading.
