claude code agent 227 7c48bab1f2 test: add unit tests for 10 candidates from issue #139
Adds co-located unit tests for ten targets (client → vitest *.test.ts(x),
server → jest *.spec.ts), plus minimal behavior-preserving extractions/exports
where the issue required a pure function to test:

- encode-wav: WAV header + PCM16 clamping
- editor-ext embed-provider / utils (sanitizeUrl, isInternalFileUrl) / indent
  (export clampIndent)
- label.dto @Matches regex
- move-page.dto vs generateJitteredKeyBetween parity (bug locked via test.failing)
- new-note-button canCreatePage (extracted to can-create-page.ts)
- history-editor diff (extracted pure computeHistoryDiff into history-diff.ts)
- notification getTypesForTab + repo contract (direct-tab divergence locked via
  test.failing)
- search buildTsQuery (extracted + sanitizes operator inputs so adversarial
  queries no longer risk a to_tsquery 500)

// only returns membership.role (not CASL permissions), so a regression here would
// either hide the button for legitimate writers or offer it to read-only members.
