Verdict: ✅ LGTM — No issues found

The fix is clean and consistent across all three parsing locations:

1. message-parser.ts:36-40 — formatMergeForwardSubMessage now handles a tags
2. client.ts:567-571 — fetchRecentMessages post parsing now handles a tags
3. event-handler.ts:2233-2236 — parseMessage post parsing now handles a tags

All three use the same formatting logic: [text](href) when both present, falling back to href or text alone. The edge cases (empty text, empty href) are handled correctly.

Minor style note (not blocking): event-handler.ts uses || '' while the other two use ?? '' for the fallback. Both work identically here since element.text/element.href will only be undefined or a string (never 0 or other falsy values), so this is purely cosmetic.

Tests: 4 new test cases cover the key scenarios (pure link, mixed text+link, href-only, text-only). Good coverage.

PR Review: fix: parse link (a tag) in post messages

Verdict: ✅ LGTM — No blocking issues

The PR expanded beyond the original a tag fix to handle all 9 post element tags (text, a, at, img, media, emotion, code_block, md, hr) and added message type placeholders. The logic is correct and well-tested.

Observations (non-blocking):

1. Code duplication across 3 files — The post element parsing logic is now copy-pasted identically in message-parser.ts:34-57, client.ts:565-588, and event-handler.ts:2220-2253. This is a pre-existing pattern (not introduced by this PR), but with 9 tag types it's becoming substantial. A shared helper function would reduce the maintenance surface. Not blocking for this PR since the scope is a bug fix.

2. || '' vs ?? '' inconsistency — event-handler.ts uses || '' while message-parser.ts and client.ts use ?? ''. Both are functionally equivalent here (string values are never 0 or false), so this is purely cosmetic. Already noted in the previous review.

3. event-handler.ts has richer img handling — It collects imageKeys for download rather than emitting [图片] placeholder, and its at handling filters out bot mentions. These are intentional contextual differences, not inconsistencies.

Tests: 20+ test cases covering all element tags, edge cases (empty text/href, mixed content), and message type placeholders. Good coverage.
