#17256: fix: allow text regex fallback when bot JID not in mentionedJids

## Summary - Remove the early `return false` in `isBotMentionedFromTargets()` that short-circuited text regex matching when `mentionedJids` contained other users' JIDs - Fix: bot now correctly responds when addressed by name even when someone else is @mentioned in the same message - Fix: WhatsApp LID mismatches no longer silently suppress mention detection — the function falls through to regex matching instead of returning false **Bug:** When a WhatsApp group message contained *any* `mentionedJids` and the bot's JID wasn't in the list, the function returned `false` immediately without attempting text-based regex matching. This meant the bot ignored messages where it was addressed by name alongside an @mention of another user, or where WhatsApp's LID→JID resolution failed. ## Test plan - [x] Updated existing test: "ignores regex matches when other mentions are present" → now expects `true` (renamed to "falls through to regex when bot JID not in mentionedJids") - [x] Added new test: "returns false when neither JID nor regex match with other mentions present" - [x] All existing tests pass (JID match, self-chat, no-mention regex fallback, LID mapping) - [x] Full test suite: 861 passed, 11 failed (all pre-existing — missing optional extension deps) <!-- greptile_comment --> <h3>Greptile Summary</h3> Removes early return that prevented text-based mention detection when `mentionedJids` contained other users. The bot now correctly responds when addressed by name even if someone else is `@mentioned`, and gracefully handles WhatsApp LID→JID resolution failures by falling through to regex matching instead of silently returning false. <h3>Confidence Score: 5/5</h3> - Safe to merge - simple logic fix with comprehensive test coverage - The change removes a premature return statement that blocked regex matching fallback, which is exactly what the bug required. The fix is minimal (removes 2 lines, adds 4 comment lines), preserves all existing behavior paths (JID matching, self-chat handling), and adds appropriate test coverage for both the fixed case and the negative case. All existing tests pass according to the PR description. - No files require special attention _{Last reviewed commit: 91733b0} <!-- greptile_other_comments_section --> _{(4/5) You can add custom instructions or style guidelines for the agent [here](https://app.greptile.com/review/github)!} <!-- /greptile_comment -->
