feat(swift-ios): copy thread metadata from row menus

[saphid]

SwiftUI thread rows now expose a Copy submenu for Path, Branch when present, and Thread ID. Actions derive their values from one copy context built from the row's current presentation context.

The refresh integrates the submenu with the native parent's current row and context-menu structure.

Verification — 5 September 2026

Head: 5d68355bb30073db809a8d0b6d196360d72a0efe. Refreshed against t3code/rebuild-mobile-app-swift at b99405468a6b2be1e0f67d551ece824b1627e35c.

ThreadCopyActionsTests: 11 passed, 0 failed; the app and test target compiled. Current-build menu and clipboard visual evidence has not been refreshed.

This PR targets the native development branch. Merging it there does not deliver it to main.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This PR adds a new production thread-row copy workflow, including clipboard writes for workspace paths and thread/environment identifiers, rather than only changing internal structure. It also adjusts environment resolution on an existing path, so the runtime and metadata-handling changes extend beyond test-only coverage.

Maintainers, this is ready for human review and classified direct against live SwiftUI target c49bcc5d8a56324eb0ad9cf1b19d5dcc6ca0caa0. None of the five changed paths overlaps Theo's new commit, and the merge-tree simulation is clean. Head 2cc5a7e28 has green required CI, 10/10 focused native tests, a successful full app/test-target Simulator build, no unresolved review threads, and successful CodeRabbit, Cursor, and Macroscope correctness reviews. The PR body now pins every image to immutable media commit 08c021141 and includes a validated clean/annotated 10.07-second proof pair.
