fix(mobile): branch search finds remote and space-typed branches

[Bil0000]

What Changed

• Mobile's new-task branch picker (checkout branch and worktree base) now uses sanitizeNewRefName for the server query and for the local filter. This is the same helper web uses. It moves from apps/web to @t3tools/shared/git, and web re-exports it, so web behavior does not change.
• The picker keeps remote-only refs and shows a remote badge on them, as web does. The server already hides origin/* refs that have a local match. Selecting a remote ref already works because switchRef creates a tracking branch.
• The filter is now a small, tested helper: filterNewTaskBranches.

Why

On mobile, the picker often could not find a branch that exists:

• Remote-only branches were hidden. Mobile removed every isRemote ref before it filtered. A branch that exists only on origin always showed "No matching branches".
• Spaces broke the query. Mobile sent the raw text to vcs.listRefs, so login page never found login-page.

Server and client matching already ignored case. The "case-sensitive" symptom came from these two gaps: the branch was never in the result set.

Verification

• vp test run on the mobile presentation tests, BranchToolbar.logic.test.ts, and packages/shared/src/git.test.ts: 104 passed. The new tests cover case-insensitive matching, remote-only refs, and typed spaces.
• tsc --noEmit passes for apps/mobile, apps/web, and packages/shared. Lint and format pass on the changed files.
• Not run on a device: no simulator was available on the host.

UI Changes

Remote-only branches now appear in the mobile picker with a remote badge. No other visual change. No screenshots: no simulator was available.

Checklist

• This PR is small and focused
• I explained what changed and why
• I included before/after screenshots for any UI changes (no simulator available)
• I included a video for animation/interaction changes (not applicable)

Summary by CodeRabbit

• New Features
  • Branch search now matches without regard to capitalization and includes remote branches.
  • Typing spaces in a search can match dashes in branch names, with surrounding whitespace trimmed.
  • Remote branches are labeled “remote” in the new-task flow.
  • Branch names are handled consistently across mobile and web, with runs of whitespace converted to dashes.

Approvability

Verdict: Approved at 25f5d01

Macroscope's review found this PR approvable — This is a focused mobile branch-picker fix that adds remote-ref visibility and consistent space/case matching while reusing existing checkout behavior. The shared helper move preserves web behavior, and the new filtering logic is covered by targeted tests.

📝 Walkthrough

Walkthrough

The shared Git module now provides ref-name sanitization. The web toolbar uses it, and mobile branch search sanitizes queries before filtering local and remote refs.

Shared ref-name sanitization packages/shared/src/git.ts, apps/web/src/components/BranchToolbar.logic.ts	The shared Git module adds sanitizeNewRefName. The web toolbar re-exports and uses it instead of its local implementation.

Remote refs receive a remote badge unless they are current or in a worktree. Tests cover query normalization and branch filtering.

Merge Risk: 🔵 Low · up to 25f5d

Space-typed searches currently work, but a regression could hide matching remote branches. Add a provider-level assertion; the remaining risk is bounded.

Add a provider-boundary assertion for sanitized branch queries.

These tests call filterNewTaskBranches directly. They do not exercise NewTaskFlowProvider's debounced request. The server performs a raw substring match, so removing the provider's normalization can omit a login-page remote ref when the user types login page. Add a provider-level assertion that the request receives login-page.

On CodeRabbit review 5307989183: no change for the provider-boundary test nitpick. NewTaskFlowProvider sanitizes branchQuery at apps/mobile/src/features/threads/new-task-flow-provider.tsx:634, debounces that value at :635, and sends it as branchTarget.query at :641-645; usePaginatedBranches passes that query to listRefs at apps/mobile/src/state/queries.ts:233-241. The current request is correct. Mobile has no provider-render test pattern, so a new harness for this wiring assertion would add more code than the behavior under test.
