fix: honor send path/filePath inputs (#1444) (thanks @hopyky)

The message tool accepts path and filePath parameters in its schema,
but these were never converted to mediaUrl, causing local files to
be ignored when sending messages.

Changes:
- src/agents/tools/message-tool.ts: Convert path/filePath to media with file:// URL
- src/infra/outbound/message-action-runner.ts: Allow hydrateSendAttachmentParams for "send" action

Fixes issue where local audio files (and other media) couldn't be sent
via the message tool with the path parameter.

Users can now use:
  message({ path: "/tmp/file.ogg" })
  message({ filePath: "/tmp/file.ogg" })
