Embedded terminal: Cmd+Left and Option+Left/Right word-movement shortcuts don't work

Feature Request / Bug Report

Summary

The embedded terminal panel inside the Claude Code desktop app does not support standard macOS keyboard shortcuts for cursor movement that work in iTerm2 and VS Code's integrated terminal.

Current Behavior

Inside the Claude Code desktop app's embedded terminal:

• Cmd+Left — no effect (does not move cursor to line start)
• Option+Left / Option+Right — no effect (does not move cursor word-by-word)

The same shortcuts work correctly in iTerm2 and VS Code's integrated terminal.

Expected Behavior

The embedded terminal should support standard macOS text navigation shortcuts:

• Cmd+Left → move cursor to beginning of line
• Cmd+Right → move cursor to end of line
• Option+Left → move cursor one word left
• Option+Right → move cursor one word right

Context

iTerm2 achieves this by sending readline-compatible escape sequences for these key combos (configurable in Preferences → Profiles → Keys). VS Code achieves it via terminal.integrated.macOptionIsMeta. The Claude Code embedded terminal appears to not pass these through or map them at all.
