fix(web): add context menu to draft threads in the sidebar

[flamboh]

Note

🤖 Opus 5.5 on behalf of Oliver

Important

Stacked on #15423; review only the top commit until it merges.

Maria reopened this after it was closed under the prior-approval rule. It is now rebuilt on current main.

Problem

Right-clicking a draft row in the sidebar falls through to the browser or desktop menu. The draft's project settings and path aren't reachable from the row.

Fix

Draft rows get a context menu, opened by right-click, the ContextMenu key or Shift+F10:

• Copy → Path / Branch: shows only the values the draft has.
• Project settings: matches the chat header's breadcrumb menu for drafts (fix(web): show project settings for new threads #9743). The item is hidden when the draft has no project.
• Discard draft: calls the shared discardComposerDraft from fix(web): discarding a sidebar draft can be undone #15423, the guard for [Bug]: Hover-only "Discard draft" X in the sidebar deletes the draft on one click, no confirmation or undo #12735. A menu discard therefore shows the same sidebar undo notice as the hover X, and Undo restores the draft. If the draft started sending while the menu was open, the discard is skipped.

The items come from a small builder, buildDraftActionMenuItems, next to the thread menu builder. It uses the shared web/desktop context menu API. There are no server, contract or mobile changes.

Before

Right-clicking a draft row shows no app menu:

After

The draft row menu:

Discard draft from the menu goes through the undo guard:

Verification

• vp test run apps/web/src/components/threadActionMenu.logic.test.ts passed (15 tests).
• vp run --filter @t3tools/web typecheck passed.
• Targeted lint and fmt reported no errors.
• Captured in headless Chromium against an isolated dev server on empty state. Undo from the menu discard restored the row.
• The native Electron menu was not exercised.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This PR adds a new draft context-menu workflow and changes discard behavior to use persisted draft restoration and deferred attachment cleanup. The in-memory cleanup window can lose attachment references across reloads or app close, leaving uploads unreleased and requiring human review.

📝 Walkthrough

Walkthrough

Draft rows now support mouse and keyboard context menus. Sidebar centralizes draft discard and context-menu actions. The menu supports conditional copying, project settings, and draft cleanup.

Changes

Draft context-menu actions

Layer / File(s)	Summary
Draft menu model and validation apps/web/src/components/threadActionMenu.logic.ts, apps/web/src/components/threadActionMenu.logic.test.ts	Adds draft menu identifiers and builds conditional copy, project settings, and destructive discard items. Tests cover unavailable actions and discard metadata.
Draft row context-menu wiring apps/web/src/components/Sidebar.tsx	Draft rows forward mouse and keyboard context-menu events, coordinates, and parent-provided callbacks through SidebarDraftBlock.
Centralized draft action handling apps/web/src/components/Sidebar.tsx	Sidebar validates draft sessions, copies paths or branches, opens project settings, releases uploads, clears drafts, and handles menu actions.

Priority: ⬇️ Low

Estimated code review effort: 3 (Moderate) | ~25 minutes

Change: Feature

Merge Risk: ⚪ Minimal · up to b3730

The new draft context-menu actions use the correct available workspace, branch, and project values, and discarding a draft does not race with promotion. No actionable merge risk remains.

🤖 GPT-6 on behalf of Oliver

Merged current main in f6f87d10ba. Scratchpad context menus retain upstream context-reference previews and use the current project workspace lookup. All 361 focused tests, web typecheck, and targeted lint pass. Conflict-resolution review found no actionable issues.

Rebuilt on current main (f90c40b). The workspace path now resolves from the project's workspaceRoot as thread rows do, and the menu items moved into a tested buildDraftActionMenuItems. Typecheck, targeted lint, and the menu tests pass.

747-750: 🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick win

Add a focused keyboard context-menu test. SidebarDraftRow maps ContextMenu and Shift+F10 to onContextMenu, which reaches handleDraftContextMenu and api.contextMenu.show. Existing buildDraftActionMenuItems tests do not render the row or dispatch either key, so they would pass if this keyboard path regressed. Test both keys and assert that the draft menu opens for the row with its draft ID and row-bottom position.

This adds Copy, Project settings and Discard actions to a new draft-row context menu without explicit maintainer scope approval. The conditional reference in #12735 does not approve this menu. Under the prior approval requirement, please discuss the draft-row discoverability problem with maintainers and link approval for the proposed menu before requesting reconsideration.
