Refactor T2: one frontmatter parser (2 hand-rolled copies)
EXECUTED 2026-07-03 (delegate stalled mid-stream at 7 read-only calls — clean tree confirmed, completed inline). Shared modules crawlers/claude_docs/fetch.py (UA/certifi/timeout/max_bytes; 3 copies eliminated) and fm.py (frontmatter incl. block scalars; 2 copies eliminated, the >- bug documented in the docstring). Gates all green: refetch smoke no-traceback, ragcache build 7412 unchanged, generate→validate→pydantic OK, IDENTITY regen byte-level no-op (parser parity proven), cm unit true, max_bytes fetch path 200. Net: ~90 duplicated lines removed, ~85 shared added once.
