Sending files through connectors now asks in a new approval dialog

What

Connectors link Claude Code to outside services. Sending files through one now has its own permission, connectorFileSend, marked as immune to bypass mode (the mode that otherwise skips permission prompts), with every other option off.

A new approval dialog for these sends:

• shows the files that would be sent
• warns when names may not be what they look like, such as non-ASCII or look-alike names
• offers only No when the list is too long, has characters that cannot be shown, or does not name the files, saying "This list of files is too long to show in full, or has characters that can't be shown as written, so it can't be approved. Choose No, and no files are sent."
• asks for a taller terminal when there is not enough room

Two smaller changes came with it:

• An attachment of invoked_skills is now treated as empty when its skills list is missing, empty or has blank entries.
• Entering plan mode with a planDoc set now restarts with planDoc cleared.

Why

Files leaving your machine through a connector now need an explicit answer, even in bypass mode, and you cannot approve a list of files you are unable to read properly.
