feat: add tool metadata to ToolVersionInfo in webhook schema (#26)

* feat: add tool metadata to ToolVersionInfo in webhook schema

Add classification, behavior, and extras metadata to ToolVersionInfo
so webhook consumers can make access-control decisions based on tool
capabilities and service domains.

New schemas: ToolVersionInfoMetadata, ToolClassification, ToolBehavior.

Made-with: Cursor

* feat: add metadata to ToolInfo for pre/post hooks

ToolInfo is used in PreHookRequest and PostHookRequest, so webhook
consumers need metadata there too — not just in the access hook path.

Made-with: Cursor

* chore: bump schema version to 1.1.0-beta
