Mark 303644f8cc docs(04-03): complete harden-clean-up-optional plan 04-03 — A29 flake fix

A29 (rrweb DOM verification) rewritten in-place via the canonical cs-
injection-world pattern + strict-sentinel filter. Closes ~2/3 flake
documented in Plans 03-02 + 03-03 SUMMARYs (A29 was "passing" by
reading iana.org leftover DOM events from A27/A28's still-open probe
tabs; a real rrweb regression at src/content/index.ts:284 would have
been masked).

Plan 04-03 task commits (atomic; sequential foreground mode):
- 73eb9b6: Task 1 — A29 page-side cs-injection-world skeleton +
  sentinel-bearing <div> injection
- b341a71: Task 2 — A29 host-side strict-sentinel filter (RESEARCH Q3
  Code Example Pattern 3); IncrementalSource added to @rrweb/types
  import binding; A29.2 PASS × 5/5 consecutive UAT runs

Empirical evidence:
- vitest 183/183 GREEN preserved (Plan 04-02 baseline)
- UAT harness 33/33 GREEN × 5 consecutive runs
- A29 strict-sentinel: mutationEvents=1, sentinelEvents=1 in ALL 5 runs
- Tier-1 FORBIDDEN_HOOK_STRINGS unchanged at 12
- SW chunk: 0 new Function, 0 eval (Plan 04-02 baseline held)
- Pre-checkpoint bundle gates 5/5 PASS

STATE.md + ROADMAP.md updated per sequential workflow:
- Plan counter advanced 3 → 4 of 7
- Progress 83% → 87% (26/30 plans complete)
- Decision log entry added for Plan 04-03
- ROADMAP Phase 4 04-03 row flipped to [x]
