chore(mops-cli): sync upstream cli-v2.16.1 → cli-v2.19.0

[marc0olo]

Syncs the mops-cli skill from the caffeinelabs/mops release cli-v2.16.1 → cli-v2.19.0 (commit be449cbeaf8b).

mops-cli has no icskills-owned body sections (.claude/upstream.md: only frontmatter differs), so all upstream additions were applied directly. After the sync the body is byte-for-byte identical to upstream.

Upstream changes applied

• [optimize] section (Binaryen wasm-opt) added to the minimal mops.toml.
• mops build: new paragraph on the wasm-opt pass (default -O3 -g), --no-optimize, and pinning Binaryen with mops toolchain use wasm-opt 131 (auto-pins latest if missing).
• mops install: --lock update / --lock check shown; prose updated — updates mops.lock by default, and the CI --lock check auto-detection is now deprecated (pass --lock check explicitly; removed in v3).
• mops add: clarifies it updates mops.toml + mops.lock even when CI is set.
• mops toolchain: added use wasm-opt, info <tool>, info <tool> --versions [--all]; agent note extended (info --versions works without mops.toml).
• New ### mops bench section (bench/*.bench.mo, --gc, --save, --compare, -- -Werror).
• Moc args layering: global args now note bench; CLI -- <flags> lists every supporting command.
• mops test: -- -Werror example added.

Other changes

• Bumped compatibility to mops >= 2.19.0.
• Removed stray </content></invoke> tags accidentally left at EOF by a prior sync (not present upstream).
• Updated .claude/upstream.md: Tag cli-v2.19.0, Commit be449cbeaf8bd9ce6c929b3ceb41591afe8bedca, Last synced 2026-07-28.

npm run validate — all 26 skills pass (warnings only).

Evals

Seeded two new output eval cases for the new commands (wasm optimization, mops bench) plus two trigger queries. Both new cases run with baseline below.

Eval results (new cases, with baseline)

Enabling Wasm optimization: WITH 4/4 | WITHOUT 4/4
  ✅ Adds an [optimize] section to mops.toml (default level O3)
  ✅ Pins Binaryen via `mops toolchain use wasm-opt 131` (or auto-pin)
  ✅ Explains the pass runs during `mops build`, and `--no-optimize` skips it
  ✅ Does NOT invoke wasm-opt manually or configure via dfx
  (baseline also 4/4 — the base model already knows [optimize]; kept as a regression net)

Running benchmarks: WITH 4/4 | WITHOUT 1/4
  ✅ Uses `mops bench` (bench/*.bench.mo)
  ✅ Uses `mops bench --save` for a baseline
  ✅ Uses `mops bench --compare`
  ✅ Does NOT invent syntax / a manual harness
  ✗ baseline fabricated a named-baseline `--save <name>` / `--compare <name>` syntax
    that mops does not support (or produced no command at all)

Closes #254
