browserrot: Node stealth sidecar + AI self-heal (M-B1..M-B3, LIVE-VM)

Extends the Phase A-tier-1 site-side rotation engine with an optional Node
browser-sidecar and a deterministic self-heal tier, all proven LIVE-VM against
the local lab change-password form. go-rod stays the default; the sidecar is a
swap-in Driver behind the same Session/Driver/Rotator interfaces — no spine
change, backup + verify-new-before-revoke-old + proof gates all apply unchanged.

M-B1 sidecar parity: internal/browserrot/sidecar/ (index.js JSON-RPC over stdio,
  patchright real-fingerprint Chromium, playwright-core fallback) + sidecar.go
  Driver/Session. A shared test harness runs go-rod and the sidecar through the
  identical live rotation proof.
M-B2 stealth: patchright removes navigator.webdriver; humanized input (Bezier
  mouse paths + per-key typing jitter, no ML trajectory generation per plan §5).
M-B3 self-heal: Healer interface + heal-retry fill/click/text wrappers; on a
  rotted selector, heal.js relocates the field from DOM structure ONLY (never a
  value) and the engine rewrites + persists the recipe (recipes.go RecipeBook)
  so the next run is Tier-1 again. Deterministic heuristic is the proven Tier-2;
  Stagehand LLM strategy is opt-in + UNPROVEN. Leak-check asserts no secret ever
  reaches a heal request (redacted IPC transcript).

Secret seam documented honestly: fill carries base64 secret bytes across exactly
one local stdio boundary, typed and wiped, never logged/persisted/sent to a
model. MFA/CAPTCHA still degrade to the human worklist (Hard Rule 5).

14 tests green, -race clean; lab/lab-provision-browserrot.sh proves both drivers.
M-B4 (first REAL self-owned site) deliberately NOT started — needs per-credential
authorization (safe-candidate ladder).
