Result / 用户结果

• Users can copy the focused pane’s working directory with Ctrl+Shift+L (Windows/Linux) or Shift+Cmd+L (macOS), same behavior as the tab context menu / command palette “Copy working directory” (clipboard + toast in GPUI when cwd is known).
• The action appears under Settings → Keymap and can be rebound or cleared like other workspace shortcuts.
• No linked issue; closes a small UX gap (action existed but had no default shortcut).

Design / 设计边界

• Responsibility: New config::Action::CopyWorkingDirectory; GPUI CopyWorkingDirectory workspace action delegates to existing TerminalView::copy_working_directory; legacy input path uses focused_cwd_string() + clipboard (same as palette CopyCwd).
• Unchanged: Tab menu, palette catalog, i18n strings (CommonCopyWorkingDirectory / CommonCwdCopied); SSH tab naming and cwd reporting rules unchanged.
• Dependencies / threading / lifetime: None; synchronous clipboard write on key dispatch.
• Compatibility: New default binding only; users with custom keybind= lines unaffected unless they override the same combo.

Evidence / 验证依据

• Commands: cargo check -p nebula --bin pebrel --features gpui-test-support — passes locally.
• Tests: Added copy_working_directory_default_binds_gpui_action and extended default-combo coverage for ctrl+shift+l; hardcoded_migration list updated. Full cargo test for pebrel not run locally (missing libxkbcommon-x11 on this machine); CI expected to run project checks.
• UI: Manual — terminal focused, cwd known → shortcut copies path and shows toast; Settings keymap row shows default combo.
• Hot path: N/A (not on render/scroll hot path).

Required Review / 必须确认

• I followed CONTRIBUTING.md, docs/architecture.md, and docs/project-constraints.md.
• I split responsibilities, not arbitrary line ranges; no duplicate behavior authority was added.
• python3 scripts/check_architecture.py --base <PR-base-commit> passes; budgets were not inflated to fit the change.
• Tests cover success and failure; platform/feature coverage limitations are stated.
• New messages use typed i18n IDs and matching placeholders; untranslated content has an explicit fallback. (Reused existing Message::CommonCopyWorkingDirectory; no new catalog IDs.)
• Governance changes include a counterexample, corrected contract, tests, and a maintainer-reviewed decision. (N/A — no governance change.)

Checkboxes explain the review; they do not replace CI or maintainer approval.

I'll fix it later when I have some free time.
