Hook matching covers PostToolBatch, and repeated refusal log entries are capped

Hooks are your own commands that Claude Code runs at set moments. The way Claude Code reads a hook's matcher, the pattern that says which tools a hook applies to, has been moved into a shared helper. That helper serves PostToolUse and now also PostToolBatch.

Separately, the remote log of tool calls (requests Claude makes to use a tool) now writes a refused request only once per day instead of every time. When later entries are skipped, the log marks that more were not written.
