GroundGuard v0.2.2

GroundGuard v0.2.2 tightens correctness and multi-tenant behavior after the
v0.2 extractor and policy expansion.

Highlights

Repeated facts with the same key now match against the latest registered
value, which prevents false contradictions after tool retries or refreshed
data.
extract_output_claims(...) and Ledger.coverage_report(...) now accept
request-scoped extractors, so services can avoid process-global extractor
mutations.
Ledger protects its in-memory indexes with a re-entrant lock for safer
parallel tool-call registration inside one session.
Matcher unit buckets are sorted and searched with bisect, reducing
same-unit candidate scans for larger ledgers.
Shadowed duplicate implementations were removed from the core extractor and
unit normalization modules.
