## Description

<!-- SECTION:DESCRIPTION:BEGIN -->
Review unresolved CodeRabbit feedback on PR #38 and implement the actionable fixes without regressing duplicate grouping or popup behavior.
<!-- SECTION:DESCRIPTION:END -->

## Acceptance Criteria
<!-- AC:BEGIN -->
- [x] #1 All unresolved actionable CodeRabbit review comments on PR #38 are triaged and either fixed in code or explicitly identified as non-actionable or ambiguous.
- [x] #2 Code changes preserve duplicate grouping and popup flow behavior covered by existing or added regression tests.
- [x] #3 Relevant local verification for the affected areas passes.
<!-- AC:END -->

## Implementation Notes

<!-- SECTION:NOTES:BEGIN -->
2026-04-01: Reopened for follow-up CodeRabbit round after commit 233bde58. Remaining actionable items: guard maxMatches <= 0 in duplicate exact-match helper and strengthen the duplicate tracking test fixture to prove deduplication as well as sorting.

2026-04-01: Follow-up round addressed locally. Added guard for maxMatches <= 0 in duplicate exact-match scanning and strengthened the pre-add duplicate tracking test fixture to prove deduplication as well as sorting.
<!-- SECTION:NOTES:END -->

## Final Summary

<!-- SECTION:FINAL_SUMMARY:BEGIN -->
Addressed all unresolved actionable CodeRabbit comments on PR #38. Fixed duplicate tracking so empty duplicate lists are not persisted after sentence-card creation, sanitized Yomitan add-note noteId values to accept only positive integers, preserved paused playback for configured subtitle-seek keybindings when pause state is unknown, and short-circuited duplicate exact-match scanning for single-result lookups. Added regression tests for each case and verified with `bun test` on the affected suites plus `bun run typecheck`, `bun run test:fast`, `bun run test:env`, `bun run build`, and `bun run test:smoke:dist`.

Follow-up CodeRabbit round addressed locally: `findExactDuplicateNoteIds()` now returns early when `maxMatches <= 0`, and the sentence-card duplicate tracking regression test now uses a repeated duplicate ID to assert deduplication plus sorting. Re-verified with targeted duplicate/card tests, `bun run typecheck`, and `bun run test:fast`.
