Boshu2 e442a414a8 fix(tests): push internal packages to 100% coverage with error-path tests ...

Add comprehensive error-path tests across all internal packages and cmd/ao.
14 packages now at 100% statement coverage; 4 remaining packages at
98-99% ceiling (provably unreachable defensive code).

Key changes:
- Add injectable test hooks (getwdFunc, marshalJSON, openFileFunc, etc.)
  to cover OS-level error branches unreachable on macOS
- Cover deferred f.Close() errors, json.Marshal failures on typed structs,
  filepath.Walk errors, and crypto/rand.Read fallbacks
- Add Linux-only build-constrained tests for filepath.Abs double-failure
- Fix flaky TestMergeWorktree_UntrackedFileDirtyRepo (100ms -> 5s timeout)
- Split ratchet_extra_test.go into per-source test files per convention
- Remove duplicate test declarations from prior agent merges
