* feat(telemetry): measure macOS stale-daemon adoption and cwd denials
Adds two enum-only PostHog events so #17696 can be sized instead of guessed at:
- daemon_adopted: once per macOS launch that keeps a daemon an earlier app
launch forked (invisible to daemon_lifecycle, which only sees replacements).
Carries app-version match, spawner-path class (installed app / Squirrel
ShipIt cache / other / missing), the existing TCC attribution verdict, and
the bucketed live-session count.
- daemon_pty_cwd_denied: the symptom itself. The daemon probes the requested
cwd in its own process (only its TCC context counts) and returns an additive
cwdReadableByDaemon field; the app emits only when the daemon was denied AND
the app can read the same path, so a missing or genuinely unreadable cwd
never counts. Non-permission errors read as readable on purpose.
Both emitters swallow every failure; nothing here can delay or fail daemon
startup or a PTY spawn. Off macOS neither event fires. The new wire field is
optional, so older daemons and clients are unaffected.
* fix(telemetry): keep cwd-denial classification inside the swallow guard
Read the pid record at emit time (inside the try) rather than passing the
adapter's startup snapshot: a throwing app-environment read can no longer
escape spawn(), and a denial after a respawn is billed to the daemon that
actually spawned the PTY.
