* fix(native-chat): retry not-yet-flushed transcripts instead of settling into a permanent error
A freshly-created session's transcript .jsonl lands on disk seconds to
minutes after the process starts. Native chat's one-shot read raced that
first flush: a miss became a permanent "No transcript found" error and
the live-tail subscription silently degraded to a no-op, so the pane
never recovered even after the file appeared.
- transcript-reader/read-cache: mark the miss with notFound so callers
can tell "not flushed yet" from a real parse/IO error (never cached).
- transcript-watch: poll resolve+install (500ms backoff, 5s cap) for the
subscription's lifetime instead of returning a dead no-op watcher.
- use-native-chat-live-session: retry a notFound read with backoff for
up to 60s while staying in the loading state, and let live appends
render over a stale initial-read error.
Fixes#8401

* fix(native-chat): address CodeRabbit review — ENOENT retryable, content over spinner, blank-id guard, unref poll timer
- transcript-reader: an ENOENT after a successful resolve is the same
first-flush/rotation race as an unresolved path — mark it notFound.
- use-native-chat-live-session: live appends landing mid-retry render
instead of the loading state (mirrors the stale-error gate).
- transcript-watch: bail out for a blank session id with no explicit
file (nothing to resolve-poll), and unref the poll timer so headless
serve shutdown is never held open by an unresolvable session.
