Add 3 routing-table rows for the new deterministic `grep_audit` intern
per .wiki/concepts/interns-grep-audit-design.md §Layer 3:
- grep_audit row — deterministic, no LLM call, zero cost
- bulk_text_read vs grep_audit boundary — Q&A vs contains-check
- always-ask uniform reminder — server opens file even sans LLM
Consistency adds: new Overview catalog row, Tool quick reference row,
prose note marking grep_audit as the catalog's first LLM-free intern.
Version 0.2.2 -> 0.3.0 (MINOR — new routing capability).
Closes [interns-grep-audit-skill-updates] on the .tasks board.
