Add 'Send to Terminal' button in VS Code extension

[rwoll]

Summary

When using the Markdown Review extension in VS Code, users can now send feedback to the terminal in addition to VS Code Copilot chat. This is useful when running Copilot CLI or other terminal-based agents.

Changes

• Core: Added onTerminal callback option and onTerminalCallback signal
• Core (NotesPanel): Added terminal icon and "Send to Terminal" button in both the panel header and footer (visible only in vscode feedbackMode)
• Core (styles): Added .panel-terminal and .panel-dl-terminal CSS classes
• Extension: Wires up terminal-feedback message handling — writes feedback text directly to the active VS Code terminal via sendText
• All modes: Clears annotations, general notes, and question answers after a successful send

Notes

• Screenshot snapshot tests will need updating in CI (the new button slightly changes page height)

@copilot - the tests are failing. please rebasline the snapshots (--update-snapshots) and commit.

@copilot - the tests are failing. please rebasline the snapshots (--update-snapshots) and commit.

Ran --update-snapshots and confirmed all 63 tests pass with the existing snapshots — no snapshot files changed. The snapshot tests only cover download feedbackMode (not vscode), so the new "Send to Terminal" button doesn't appear in any of the captured screenshots and the snapshots were already up to date.

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
