claude-hooks v1.20.2

Fixed

• The hook daemon held 20.9 GB (plus 4.3 GB of swap) on solidpc. The
  Stop hook parsed the whole transcript into memory on every turn, and
  the task nudge read it whole as one string, to look at the last turn.
  Long-lived sessions' transcripts are gigabytes (opencoti 5.2 GB,
  backup_models 4.5 GB). Python freed it, but glibc kept the pages, so
  the daemon stayed at its largest turn: malloc_trim(0) took it to
  312 MB. New claude_hooks/transcript_tail.py reads backwards in
  growing windows until the turn's opening prompt (128 MB cap); on the
  5.2 GB transcript a Stop read is 43 ms and 41 MB. SessionEnd's
  episodic push streams the file instead of reading it into memory.
• Task state no longer lives in the project's task folder. The hook
  daemon runs with ProtectSystem=strict and only ~/.claude writable,
  so the reconcile cache (.index-state.json) failed with
  Read-only file system on every write there, and the Stop-nudge memory
  and the built-in-task map would have failed the same way. All three
  now live in ~/.claude/claude-hooks-tasks/<project>-<hash>/
  (CLAUDE_HOOKS_TASKS_STATE_DIR overrides it); a copy left in a task
  folder is read once and removed.
