Fix Start auth server peer tracing

[zbeyens]

• Auto release

🐛 Fixes local package bug (no tracker issue)
🟢 95-100% confidence

Phase	🧪 Tests	🌐 Browser
Reproduced	🔴 bun test packages/kitcn/src/auth-start/index.test.ts --test-name-pattern 'statically traceable'	➖ N/A
Verified	🟢 targeted auth/start tests, package build, typecheck, lint, bun check	➖ N/A

✅ Outcome

• kitcn/auth/start now statically imports @tanstack/react-start/server.
• Declared @tanstack/react-start as optional peer + package dev dependency.
• Added regression coverage for the traceable import.
• Updated changeset and captured the solution note.
• Fixture sync updated Expo package patch versions.

⚠️ Caveat

• No browser surface changed.

🏗️ Design

• Chosen seam: package entrypoint import graph.
• Why not quick patch: app-level Nitro traceDeps would force every Start user to patch around kitcn.
• Why not broader change: kitcn/auth/start is already the framework-specific surface; no API redesign needed.

🧪 Verified

• bun test packages/kitcn/src/auth-start/index.test.ts --test-name-pattern 'statically traceable' fails before fix.
• bun test packages/kitcn/src/auth-start/index.test.ts packages/kitcn/src/auth-start/index.retry.test.ts
• bun --cwd packages/kitcn build
• rg -n "@tanstack/react-start/server|import\\(" packages/kitcn/dist/auth/start/index.js packages/kitcn/src/auth-start/index.ts
• bun lint:fix
• bun typecheck
• bun test packages/kitcn/src/package-intent.test.ts --test-name-pattern 'declares intent metadata'
• GIT_TERMINAL_PROMPT=0 bun check

Add fixture path mapping for new start server subpath

Switching this fixture to kitcn/auth/start/server introduces an unresolved import in local fixture/scenario runs that rely on tsconfig path rewrites to source files: tooling/fixtures.ts only maps kitcn/auth/start (not the new /server subpath), so Vite/TS falls back to package exports and looks for packages/kitcn/dist/auth/start/server/index.js, which is absent in a fresh checkout unless packages/kitcn has been built first. This breaks scenario:prepare/fixture dev flows in clean environments; add a matching kitcn/auth/start/server mapping in fixture path generation.
