fix(desktop): preserve fresh-session title routing

[Studio729]

Summary

• treat an explicitly remembered New session route as authoritative over a stale last-session ID
• clear stale remembered session identity when a deliberate fresh draft is active
• preserve legitimate cold-start session restoration during the transient initial / render
• add regression coverage for both routing invariants

Verification

• cd apps/desktop && npm run check
• 229 test files passed; 1,948 tests passed; 2 skipped
• desktop artifact tests, macOS DMG packaging, and production build passed

Manual regression

1. Open a titled session.
2. Start a New session.
3. Restart Hermes Desktop.
4. Confirm the New session does not inherit the older title.

Thanks for the focused regression fix. The premise is confirmed on current main: use-desktop-integrations.ts:64-72 persists the initial / route before the restore effect at :79-99 runs, allowing the stale last-session fallback at :95-99 to win after a user deliberately starts a new draft. use-session-actions/index.ts:226-235 confirms that fresh-draft flow clears route intent and navigates to / with no routed session ID.

The change in 0652714a182c makes / authoritative, preserves the transient / render while a valid restore navigation is pending, and adds focused coverage for both invariants. No blocking problems identified.

Rebased onto current main (dd418284d).

• 1 commit replayed cleanly (no conflicts)
• Tests: apps/desktop vitest use-desktop-integrations.test.tsx → 2 passed
• Ready for CI + maintainer review/merge

[Studio729]

Rebased cleanly onto current main (1b8e34e94); this branch is 0 commits behind at this update.

• Head: ecdebfc51
• Verification: Desktop vitest: 2 passed; npm run typecheck: passed. Final replay was clean.
• Upstream CI is action_required; a repository maintainer must approve the fork workflow run before checks can execute.

Ready for maintainer review.

Closing as intentionally abandoned.

Tim is standardizing on the managed Hermes install (hermes update + /Applications/Hermes.app) and retiring the local Desktop release-train / dual-runtime dogfood path. These Studio729 PRs were carried for that local composed train; the maintenance cost outweighed the remaining value while they were blocked on maintainer/CI gates.

Happy to reopen a focused follow-up later if a specific fix is still needed on current main.
