v1.30.0

What's Changed

• chore: sync version 1.29.1 to staging by @rapiercraft-forgedock[bot] in #4324
• chore(lean): 1.30.0 staging review delta-pass LOW follow-ups (batched) (review finding — PR #4314) (#4318) by @rapiercraft-forgedock[bot] in #4326
• lean: contract validation commands fail on missing host tools and are reported as conformance.unimplemented (terminal) instead of an environment error (#4323) by @rapiercraft-forgedock[bot] in #4329
• fix(pipeline): lanes miss exhaustiveness guard tests and collide on sequence-numbered migrations (#4322) by @rapiercraft-forgedock[bot] in #4330
• fix(lean): conformance review mangles evidence paths containing parentheses (Next.js route groups) → review.incomplete (#4327) by @rapiercraft-forgedock[bot] in #4332
• perf(lean): pre-PR checks run every learned command serially on the whole repo — 14-25 min precheck waits per lane on 1.29.1 (#4331) by @rapiercraft-forgedock[bot] in #4335
• lean: redGreen repro check runs without the run TMPDIR — builder-created $TMPDIR files vanish, repro reports BASE=SKIPPED HEAD=FAILED (#4325) by @rapiercraft-forgedock[bot] in #4333
• follow-up: 1 deferred item(s) (deferred from #4323) (#4328) by @rapiercraft-forgedock[bot] in #4336
• fix(lean): conformance repro check reports UNRUNNABLE for repro tests that need workspace deps, and SKIPPED-on-base for new test files (#4334) by @rapiercraft-forgedock[bot] in #4338
• feat(lean): close decomposed parents after decomposition; closed decomposed parents still gate dependents through their sub-issues (#4337) by @rapiercraft-forgedock[bot] in #4339
• fix(lean): honour decomposition.close_parent on the lean path; 1.30.0 config docs and recoverable env codes (release review #4340) by @rapiercraft-forgedock[bot] in #4341
• Release: lane-env repro and validate checks, recoverable env codes, scoped parallel pre-PR checks, decomposed parents close by @rapiercraft-forgedock[bot] in #4340
