* fix(2112): scope commit to --files pathspec, not entire index
cmdCommit/cmdCommitToSubrepo/cmdPrSubrepo staged exactly the files
named in --files but then ran a bare 'git commit' with no pathspec,
absorbing anything else in the index into a commit whose message
described only the named files (#2112).
Fix: append '-- ...stagedPaths' to the commit args when the caller
declared a scope. Three guards are load-bearing:
- stagedPaths (not filesToStage) excludes skipped missing files (#2014)
- explicitFiles gate keeps the default .planning/ path byte-identical
- MERGE_HEAD check via 'git rev-parse' falls back to bare commit during merge
- --amend is left without pathspec (different operation)
cmdPrSubrepo pathspec uses changedFiles (old+new for renames) so the
full rename is captured atomically.
Also fixes workflow markdown in spec-phase.md and add-tests.md.
All-files-missing now short-circuits to nothing_to_commit instead of
absorbing the entire index under a message describing files that
were not committed.
* docs(changeset): backfill PR number (#2148)
* test: update golden-install-parity fixtures for workflow markdown changes (#2112)
* test: update golden fixtures + workflow baselines for #2112 changes
- claude-local.json golden fixture (now generated via gen script)
- workflow-size-baseline.json (add-tests.md +16, spec-phase.md +42 bytes)
- Extended gen-golden-install-parity-zcode.cjs to also regenerate the
claude local-layout fixture
