Factory takes [[ErrorCtor, TRPC_CODE], ...] tuples and returns a tRPC
middleware that translates matching domain errors to TRPCError. Discrim-
inates by instanceof; preserves original error as cause; unmapped
errors propagate (tRPC then wraps them as INTERNAL_SERVER_ERROR with
the original error as .cause — middleware does not interfere).
core-shared never enumerates feature errors — each feature passes its
own constructors in via integrations/api/procedures.ts (Tasks 3-7).
Also exports the `t` instance from trpc/init.ts so feature procedure
files can do t.procedure.use(...).
Also fixes tsconfig.json: rootDir set to "." and @/* path alias added
so test files using @/ resolve correctly under tsc --noEmit.
Refactor log: §1, §2, §4
Spec: R13–R17
Aligns tooling packages with the core-* naming convention used by all
other foundation packages (core-shared, core-cms, core-api, core-trpc,
core-ui). Updates ~50 files: package.json names, devDependencies,
tsconfig extends, eslint.config imports, vitest.config imports, AGENTS.md
references, and the boundaries plugin patterns to match the new paths.
The tooling-specific patterns in boundaries/elements are now ordered BEFORE
the broader core-* pattern to ensure correct first-match-wins behavior.
