Implements the lifecycle-aware-doc-hygiene change (ADR-0038..0041):
rulebook loader (global rulebook.json + per-project .dochygiene-rules.json,
add-only merge, two-axis precedence, IGNORE-sentinel zero-emission prune),
scanner lifecycle signals + temporary/delete-once-served tiers, report
schema delete/extract-then-delete ops with git-state tier derivation,
promotion_candidates from conventions.json, patch-applier deletion ops with
apply-time git re-verification, and the /os-doc-hygiene:calibrate skill.
Calibration pass #1 (cc-os) PASSED: protected-set hard gate + recall floor
9/10 with all 4 mandatory rows; 4 human-approved rules persisted to
repo-root .dochygiene-rules.json. invariants.md #3 (.cc-os/dochygiene per
ADR-0027) and #9 (rulebook IGNORE as third ignore mechanism) corrected
with explicit human approval per the META-RULE.
test_no_global_index_created now runs against an isolated HOME (the real
~/.cc-os legitimately exists since os-backlog's projects registry).
Suite: 408 passed.
