Add inline "Learn more" link in the install message that opens
the Claude Code product page. Style the link to match the panel
theme.

Add options.shellCommand parameter to VIEW_TERMINAL command to
open a new terminal and execute a command in it. Add installing
and installing-message strings. Add learn-more link styling.

checkAvailability now returns loggedIn flag via claude auth
status. Add setup/login strings for Claude Code configuration
screen.

Remove getQueryFn() call from checkAvailability — CLI presence
and auth status are sufficient. Add custom provider button string
and spacing fix for setup screen buttons.

Add explicit color to inline code elements using panel text
color. The sidebar is always dark regardless of editor theme,
so code blocks need to use panel text colors not body text.

Wait for shell prompt before writing command instead of firing
immediately after PTY spawn. Use \r (carriage return) instead of \n
for command submission, matching what xterm.js sends for Enter.

Intercept EnterPlanMode/ExitPlanMode tools from Claude Code SDK.
Capture plan content from Write to .claude/plans/, display as a styled
card with Approve/Revise buttons. On approve, send follow-up prompt to
proceed with implementation. On revise, abort and send user feedback as
a new prompt. Includes i18n strings and plan card CSS.

Plan files written to .claude/plans/ are now intercepted early in the
Write hook — content is captured for the plan card UI but the file is
not opened in the editor, avoiding clutter from out-of-project files.

Tell Claude about execJsInLivePreview and takeScreenshot in the system
prompt so it can include meaningful verification steps when planning.

Only suggest execJsInLivePreview and takeScreenshot for verification
when working with HTML/CSS/JS in live preview, not generically.
