tracker-github: cache gh issue view responses in-process (5 min TTL, bounded LRU)

The lifecycle worker polls getIssue and isCompleted repeatedly for the same
issue across a session. In a 5-session tier-5 bench run (10 min), trace data
showed the same (repo, issue) pair fetched 64+ times with >97% duplicate rate.

This change caches the full Issue object per (repo, identifier) for 5
minutes inside each createGitHubTracker() instance. isCompleted now routes
through getIssue to share the cache. updateIssue invalidates the cache
entry on any mutation. Failures are not cached.

Expected reduction: ~744 gh issue view calls per tier-5 run → ~15 calls.
