VSCode extension: keyboard shortcuts (/, ctrl+p, ctrl+b, etc.) not working in webview panel #26519

Description

Description

When using the OpenCode VSCode extension (not the terminal/TUI version),
keyboard shortcuts defined by OpenCode do not work because VS Code intercepts
them before they reach the webview panel.

Environment

• OpenCode version: (your version)
• VS Code version: (your version)
• OS: Windows

Shortcuts affected

• / (slash) — intercepted by VS Code comment action
• ctrl+p — intercepted by VS Code "Go to File"
• ctrl+b — intercepted by VS Code sidebar toggle
• ctrl+j — intercepted by VS Code panel toggle
• ctrl+r — intercepted by VS Code "Open Recent"
• ctrl+z — intercepted by VS Code undo

Steps to reproduce

1. Install the OpenCode VS Code extension
2. Open the OpenCode panel
3. Click inside the OpenCode webview to focus it
4. Try pressing / or ctrl+p
5. VS Code handles the shortcut instead of OpenCode

Expected behavior

Shortcuts should be captured by the OpenCode webview when it is focused.

Actual behavior

VS Code intercepts the keypresses and triggers its own commands instead.

Notes

This is a known VS Code webview limitation (microsoft/vscode#129178) but it
can be worked around by the extension using webview keyboard event handling.
Other extensions like Cline and Continue have implemented similar workarounds.
The terminalFocus when-condition does not apply here since the extension uses
a webview panel, not a terminal.
