Maurice Böe 942e1932c9 fix(budget): name the category parking and file parking bookings in it
The key was 'parkings', which is not a word and does not match the 'parking'
the reservation type uses everywhere else. The shared trip page prints the
stored category verbatim, so a share link would have shown "parkings" in every
language.

The category also had no relationship to the booking type of the same name:
RESERVATION_TYPE_TO_COST_CATEGORY still sent a parking booking's auto-expense
to Transport, so the new bucket sat empty next to the costs that belong in it
while a manually typed "parking" resolved into it. Both paths agree now.

@trek/shared

Single source of truth for TREK's API contracts, expressed as Zod schemas and consumed by both the server (request validation + inferred DTO types) and the client (typed requests/responses).

This package is part of the incremental NestJS + React 19 migration (see the "Brownfield Rewrite" board). It is intentionally dormant until modules start importing it — adding it changes nothing for users.

Rules

  • One folder per domain: src/<domain>/<domain>.schema.ts (+ .spec.ts).
  • Domain-agnostic building blocks live in src/common/.
  • A route is only considered migrated once its contract lives here.
  • Schemas are the source of truth; server DTOs and client types are inferred from them (z.infer<typeof schema>), never hand-duplicated.

Consumption (dev)

Both apps resolve @trek/shared to this package's TypeScript source:

  • Server (tsx): via paths in server/tsconfig.json.
  • Client (vite): via resolve.alias in client/vite.config.ts (+ paths for the type-checker).

Production packaging (Docker / workspace wiring) is introduced in card F2, when the server first depends on this package at runtime. Until then prod builds are untouched.

Not yet here

The canonical error envelope is finalised in card F5 (it must match TREK's current Express error responses byte-for-byte), so it is deliberately not invented in F1.
