refactor(navigation): unify use-case I/O schemas + presenter + feature error map
Per Plan 9 (spec R1-R28):
- getHeader use case: input z.object({}).strict() (R5); output =
headerSchema parsed at runtime.
- getHeader controller: unknown input + identity presenter.
- New integrations/api/procedures.ts with navigationProcedure
([InputParseError → BAD_REQUEST], [HeaderNotFoundError → NOT_FOUND]).
- Router uses navigationProcedure + .input(getHeaderInputSchema).
- src/index.ts: remove headerQuery; export schemas + IUseCase/Controller
aliases.
- src/ui/index.ts (NEW); package.json adds ./ui subpath.
- R25 + R26 tests added.
