Walkthrough

Adds Cmd+Left and Cmd+Right handling in the terminal keyboard handler to send Ctrl+A/Ctrl+E via onWrite, and remaps several global hotkeys to include different modifier combinations to avoid conflicts with terminal line navigation.

Changes

Cohort / File(s)	Summary
Terminal keyboard handler apps/desktop/src/renderer/screens/main/components/WorkspaceView/ContentView/TabsContent/Terminal/helpers.ts	Added handling for Meta+ArrowLeft and Meta+ArrowRight that call onWrite with Ctrl+A and Ctrl+E respectively (keydown), returning false to stop further processing. Inserted after existing Cmd+Backspace branch.
Hotkey definitions apps/desktop/src/shared/hotkeys.ts	Remapped navigation hotkeys: PREV_TERMINAL and NEXT_TERMINAL changed to meta+alt+left/right; PREV_PANE and NEXT_PANE changed from meta+alt+left/right to meta+shift+left/right.

Poem

🐰 Cmd and arrows tap-tap, off I hop,
Ctrl+A and E make the cursor stop,
Alt and Shift rearrange the dance,
No more clashes — give the keys a chance! 🥕

However, the PR objectives mention Cmd+Option+Up/Down for pane switching while the hotkeys.ts summary shows meta+shift for pane navigation, indicating a discrepancy.	Clarify whether pane switching uses Cmd+Option+Up/Down or Cmd+Shift+Up/Down, as the PR objectives and file changes show conflicting information.
