Add fullscreen window display mode for page actions

[Copilot]

Adds fullscreen as a fifth display mode option for page action commands, alongside popup, window, tab, and background tab.

Changes

Core Implementation

• Added FULLSCREEN = "fullscreen" to PAGE_ACTION_OPEN_MODE enum (shared package)
• Fullscreen is page-action-only; not available for search commands
• Implementation: create POPUP_TYPE.NORMAL window, then apply chrome.windows.update(windowId, { state: "fullscreen" })

Services (packages/extension/src/services/pageAction/background.ts)

• openAndRunPageAction: handles fullscreen mode during execution
• openRecorder: supports fullscreen mode when recording actions

UI (packages/extension/src/components/option/field/OpenModeToggleField.tsx)

• Dynamic grid layout: 4 columns for search, 5 columns for page actions
• Added fullscreen icon mapping and selection option

Localization

• Added fullscreen translations across all 14 supported languages

Example Usage

When creating or editing a page action command, users can now select fullscreen mode:

// Internally, when openMode is FULLSCREEN:
const w = await chrome.windows.create({
  url: startUrl,
  type: POPUP_TYPE.NORMAL,
  // ... other params
})

if (openMode === PAGE_ACTION_OPEN_MODE.FULLSCREEN && w.id) {
  await chrome.windows.update(w.id, { state: "fullscreen" })
}

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• www.google-analytics.com
  • Triggering command: /opt/hostedtoolcache/node/24.13.0/x64/bin/node /opt/hostedtoolcache/node/24.13.0/x64/bin/node --conditions node --conditions development /home/REDACTED/work/selection-command/selection-command/node_modules/tinypool/dist/entry/process.js (dns block)

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)
