feat: Terminal auto-approve with confirmation dialog enhancement (Auto-approve Part 2)

[xinyi-gong]

Adds terminal command auto-approve rules with preference UI, session/global persistence, and a split-dropdown confirmation dialog for granular approval actions (allow command name, exact command, or all commands per session).

Pull request overview

Adds terminal command auto-approval configuration and persistence, plus a richer tool-confirmation UI that supports session/global “allow” actions. This extends the agent tool confirmation pipeline to evaluate auto-approve rules, synchronize them to the Copilot language server settings, and render a split-dropdown confirmation dialog.

Changes:

• Introduces a new “Tool Auto Approve” preference page/section for managing terminal allow/deny rules and an “unmatched commands” toggle.
• Adds terminal confirmation evaluation + persistence (session/global) and wires preference changes into CLS settings sync.
• Refactors the confirmation dialog UI to use ConfirmationContent/ConfirmationAction and a split-dropdown primary action.
