Document the lexical limit scope.

In src/shell/grep-core.ts, memLexQuery and sessLexQuery each apply LIMIT lexicalLimit. The combined query can therefore include two lexical batches before the outer limit is applied. State that HIVEMIND_HYBRID_LEXICAL_LIMIT applies per source/table, or enforce one global lexical cap.

Suggested wording 
- capped by `HIVEMIND_HYBRID_LEXICAL_LIMIT`
+ capped per source by `HIVEMIND_HYBRID_LEXICAL_LIMIT`

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

In `@README.md` at line 45, Update the README search description to clarify that
HIVEMIND_HYBRID_LEXICAL_LIMIT applies separately to each lexical source/table,
since memLexQuery and sessLexQuery each apply the limit before the combined
query’s outer limit.
