fix(web): launcher shortcuts no longer hijack the empty composer

[Lucenx9]

What Changed

The right-panel empty-state launcher's capture-phase keydown handler now treats every contenteditable as a typing context, whether or not it has text. Extracted the guard into an exported, unit-tested helper (surfaceShortcutTargetsTypingContext).

Why

The handler skipped input/textarea/select and non-empty contenteditables, but deliberately let an empty contenteditable through - which is the chat composer's normal at-rest state. Clicking into the composer and starting a prompt with t, b, f, d, p, or a instead triggered the launcher: for T that opens a terminal in the workspace, autofocuses it, and the remainder of the prompt plus any Enter presses go to the live shell via terminalWrite - accidental command execution and prompt leakage into shell history.

This also contradicted the component's own documented contract ("opens it directly from anywhere outside a typing context"): a focused editable is a typing context even when empty. Launcher letters keep working from any non-editable focus; type-to-focus suppression for launcher keys (ChatView) is unchanged and still correct for that path.

Found by an automated security review (assessed low/same-user); fixed as a UX/input-safety bug.

Note

Medium Risk
Changes capture-phase keyboard shortcut routing that previously could open a terminal and send leftover keystrokes into a live shell. Scope is small and well-tested, but it sits on a global keydown path.

Overview
Right-panel launcher letter shortcuts no longer fire while the chat composer (or any other editable) is focused, even when it is empty.

The capture-phase handler used to skip only form fields and non-empty contenteditables, so typing t/b/f/etc. into an at-rest composer opened a surface (and for T, dumped the rest of the prompt into a live shell). The guard now treats every input, textarea, select, and [contenteditable] (except contenteditable="false" islands) as a typing context, matching the composer pending-input shortcut guard. Extracted as surfaceShortcutTargetsTypingContext with unit tests. Shortcuts still work from non-editable focus.

Note

Fix RightPanelEmptyState shortcuts to ignore typing contexts

• Adds surfaceShortcutTargetsTypingContext to identify if focus is inside an input, textarea, select, or editable contenteditable host.
• Updates the RightPanelEmptyState keydown handler to use this utility and exit early, preventing letter shortcuts from triggering while typing.
• Behavioral Change: Widens the instanceof guard in RightPanelEmptyState from HTMLElement to Element.

Summary by CodeRabbit

• Bug Fixes
  • Improved keyboard shortcut handling so shortcuts no longer trigger while typing in input fields, text areas, dropdowns, or content-editable areas.
  • Ensured empty chat composer fields are correctly treated as typing contexts.
• Tests
  • Added coverage for shortcut behavior across editable and non-editable focus targets.

📝 Walkthrough

Walkthrough

The PR adds surfaceShortcutTargetsTypingContext to detect editable targets. The global shortcut handler uses this helper, and tests cover form fields, contenteditable targets, non-editable targets, and null targets.

Changes

Shortcut Typing Context

Layer / File(s)	Summary
Typing context helper apps/web/src/components/RightPanelTabs.tsx, apps/web/src/components/RightPanelTabs.test.tsx	The exported helper detects input, textarea, select, and [contenteditable] targets.
Shortcut handler integration and tests apps/web/src/components/RightPanelTabs.tsx, apps/web/src/components/RightPanelTabs.test.tsx	The shortcut handler uses the shared helper. Tests validate editable, non-editable, and null targets.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🔵 Low · up to 19e0f

The change prevents launcher shortcuts from hijacking editable input, but non-editable contenteditable="false" regions may now incorrectly suppress those shortcuts. This is a bounded correctness risk that is mergeable with explicit owner follow-up.

One finding on the new typing-context helper: the "nearest match, then check the attribute" shape answers false for targets nested inside a contenteditable="false" island that itself sits inside the editable composer, which re-opens the keystroke-hijacking case this PR fixes. The repo already has an idiom for this (ComposerPendingUserInputPanel) that covers both goals in the selector.
