feat(mobile): long-press file references for path and open actions

[juliusmarminge]

What changed

• File chips in iOS messages get a native long-press context menu with Copy full path, Copy relative path, and Open in file viewer, the same actions the web chip offers on right-click.
• T3MarkdownTextRun accepts a JSON contextMenuConfig; T3MarkdownText maps runs that carry one to UITextItem links so iOS 17's text-item menu owns the gesture. Tap and text selection keep working; text drag is disabled on chat text.
• SelectableMarkdownText gains fileContextMenu and onFileContextMenuAction. The feed builds the menu description and runs actions from one handler at the root, so rows subscribe to nothing extra per chip.

Why

Tapping a file reference opened it and that was the only thing you could do with it. Users copying a path had to open the file first. Web has had a chip context menu for a while; this brings the same set to iOS through UIKit rather than a JS action sheet.

Split out of #9253 so the media refactor there stays a refactor.

UI changes

Before: tap only	After: native context menu
No long-press affordance on file chips.

Testing

• fileChipMenu.test.ts (5 tests)
• Mobile typecheck, lint, and format on changed files

Medium Risk
Touches native gesture handling and iOS 17 text-item menus on chat text; disabling text drag and suppressing recognizers on menu runs could affect edge-case interactions outside file chips.

Overview
Adds native long-press context menus on iOS for inline file references in chat markdown, matching web chip actions: copy full path, copy relative path, and open in the file viewer.

The t3-markdown-text native layer now accepts a JSON contextMenuConfig on text runs, builds a UIMenu, and wires T3MarkdownText (iOS 17 text-item delegates) so menu runs are exposed as links while custom tap/long-press is skipped on those runs. Chat UITextView also disables text drag. SelectableMarkdownText gains fileContextMenu / onFileContextMenuAction plus a React context so file chips in the tree share one handler.

ThreadFeed centralizes tap and menu behavior in markdownLinkHandlers via new fileChipMenu / resolveFileChipTarget. resolveWorkspaceRelativeFilePath now rejects paths that escape the workspace with .. (e.g. /repo/../outside.txt). User docs note iOS touch-and-hold on file references.

Note

Add long-press context menu for file references in mobile markdown text

• Native iOS T3MarkdownText and T3MarkdownTextRun build context menus from a serialized JSON config and emit a native event when an action is selected. Custom tap/long-press recognizers are suppressed on runs with a menu, while other runs keep existing gesture handling.
• React Native wiring in SelectableMarkdownText.ios.tsx and ThreadFeed.tsx resolves file-chip hrefs to menus and dispatches copy-path and open-file actions.
• fileChipMenu.ts classifies file links into full and relative paths and builds a menu with only the supported copy actions plus the file-viewer open action.
• filePath.ts now rejects absolute targets that escape the workspace via a .. segment instead of normalizing them.
• Risk: disabling drag interaction on T3MarkdownText means text drag-and-drop no longer works on iOS; handleLongPressIfNecessary now fires once at the began state rather than across all long-press transitions.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This adds a new iOS long-press workflow through native UIKit text-item menus and bridges actions into production message rendering. It also disables text drag-and-drop and changes gesture handling for the shared markdown text component, giving the change a broader interaction surface than a simple UI adjustment.

What changed

• File chips in iOS messages get a native long-press context menu with Copy full path, Copy relative path, and Open in file viewer, the same actions the web chip offers on right-click.
• T3MarkdownTextRun accepts a JSON contextMenuConfig; T3MarkdownText maps runs that carry one to UITextItem links so iOS 17's text-item menu owns the gesture. Tap and text selection keep working; text drag is disabled on chat text.
• SelectableMarkdownText gains fileContextMenu and onFileContextMenuAction. The feed builds the menu description and runs actions from one handler at the root, so rows subscribe to nothing extra per chip.

Why

Tapping a file reference opened it and that was the only thing you could do with it. Users copying a path had to open the file first. Web has had a chip context menu for a while; this brings the same set to iOS through UIKit rather than a JS action sheet.

Split out of #9253 so the media refactor there stays a refactor.

UI changes

Before: tap only	After: native context menu
No long-press affordance on file chips.

Note

Medium Risk
Touches native gesture handling and iOS 17 text-item menus on chat text; disabling text drag and suppressing recognizers on menu runs could affect edge-case interactions outside file chips.

Overview
Adds native long-press context menus on iOS for inline file references in chat markdown, matching web chip actions: copy full path, copy relative path, and open in the file viewer.

The t3-markdown-text native layer now accepts a JSON contextMenuConfig on text runs, builds a UIMenu, and wires T3MarkdownText (iOS 17 text-item delegates) so menu runs are exposed as links while custom tap/long-press is skipped on those runs. Chat UITextView also disables text drag. SelectableMarkdownText gains fileContextMenu / onFileContextMenuAction plus a React context so file chips in the tree share one handler.

ThreadFeed centralizes tap and menu behavior in markdownLinkHandlers via new fileChipMenu / resolveFileChipTarget. resolveWorkspaceRelativeFilePath now rejects paths that escape the workspace with .. (e.g. /repo/../outside.txt). User docs note iOS touch-and-hold on file references.
