Summary

• add explicit glob and regex matchers for arbitrary when.toolArgs values while preserving exact matching
• expose direct tool arguments to inject/toast templates and hook commands through a private temporary JSON file
• prefer arguments from modern after-hook events and isolate fallback caches by plugin, session, and call
• document the behavior and cover matching, interpolation, shell safety, large payloads, cleanup, and concurrency

Closes #12
