feat: implement SDK/HTTP pruning for deduplication and tool-output truncation on SQLite

- executeDeduplication: now async, reads messages from SDK on SQLite via
  client.session.messages() instead of JSON file reads
- truncateToolOutputsByCallId: now async, uses truncateToolResultAsync()
  HTTP PATCH on SQLite instead of file-based truncateToolResult()
- deduplication-recovery: passes client through to both functions
- recovery-hook: passes ctx.client to attemptDeduplicationRecovery

Removes the last intentional feature gap on SQLite backend — dynamic
context pruning (dedup + tool-output truncation) now works on both
JSON and SQLite storage backends.
