fix: housekeeping sweep — telemetry integrity, persistent opt-out, context-bill accuracy, setup hang, dev-server discovery, model resolution (#2136 + v1.63 polish)

Seven small fixes, one theme (claims matching code):
- telemetry-sync strips local-only fields with jq del() (structural) instead
  of quote-fragile sed regexes; unparseable lines are dropped, never
  forwarded unstripped. Sed survives only as a jq-less fallback.
- telemetry-log rejects non-integer durations BEFORE the range caps, whose
  test(1) comparisons silently no-op on non-numerics — a malformed duration
  spliced raw text into the JSONL stream.
- browse's local telemetry honors the persistent tier (config.yaml
  telemetry: off), not just the preamble's env hint — direct $B use and
  embedders now respect the opt-out.
- gstack-context-bill --exact sees GSTACK_-promoted keys inside Conductor
  (conductor-env-shim wired at the CLI entry), and the TOTAL line no longer
  double-counts every nested skill through the root skill's walk (v1.63
  deferred polish; the telemetry-sync HTTP-status outcome deferred alongside
  it turned out already shipped).
- setup's Chromium probe is deadline-bounded (90s, background + poll-kill —
  macOS has no GNU timeout) and prefers Node for the launch probe everywhere
  (the bun --eval hang family behind #2136); the install is single-flight
  behind a lock dir with an actionable stale-lock message. Probe verified
  live on this Mac.
- the review resolver's dev-server check reads CLAUDE.md and the plan file
  before falling back to an expanded port probe, and says how to make
  itself smarter next time.
- eval/harness model IDs resolve through lib/eval-model.ts
  (GSTACK_EVAL_MODEL[_KIND] env overrides, per-kind defaults, tested) at the
  SDK-capture and PTY-warmup sites; the bash-embedded distill snippet
  mirrors the resolution inline.
- memory-ingest's silent-zero shape (staged>0, imported+unchanged==0,
  errors==0) warns even under --quiet — a run that indexes nothing must
  never look healthy again.
