feat(lark-doc): add synonym rewriting and bitable/wiki drill-down rules

[arnold9672]

Summary

• Add synonym rewriting rule: enforce 1-2 rounds of synonym/near-synonym rewriting for topic-style queries before locking an answer, covering expected sources with alternate title phrasings
• Add BITABLE/WIKI drill-down rule: inspect semantic fields (tags, summary, description) beyond just title when drilling into bitable records or wiki sub-nodes after docs +search hit

Test plan

• Verify topic-style search queries (e.g. "XX 优秀案例") trigger synonym rewriting rounds
• Verify BITABLE hits drill down into non-title fields via base +field-list
• Verify WIKI hits inspect sub-node structure via wiki +node-list
• No regression on existing search decision rules

Poem

🐰 Through synonym woods we hop and bound,
Each round converging to solid ground,
WIKI fields whisper their hidden tale,
Beyond mere titles, we will not fail! ✨
