V47 Gate 10: Repair promoted-family rewrite ordering

Fix the V47 promoted-family rewrite in
prepare-bitcode-spec-family-promotion.mjs: earlier substring rules
('until V47 promotion', 'V47 draft work') rewrote text before the longer
exact draft-posture rules could match, leaving two orphaned
"V46 remains active canon" fragments that failed the promoted spec-family
stale-phrase scan during the promote step (which correctly failed closed
before committing). Add orphan-specific rewrites plus a final catch-all so
no "V46 remains active canon" fragment can survive promotion.

Validated with a full local promote-step simulation: spec-family promotion
preparation, pointer flip, runtime promotion preparation, promoted
spec-family check, promoted PROVEN regeneration (16 runs, fullyProven=true),
canonical inputs for V47, and canon posture drift V47/V48 all pass; draft
state restored afterward. Regenerate the promotion readiness artifact
against the repaired script digest; check:v47-gate10 passes including the
promotion dry-run.
