:boom: Modernize the toolchain and ship dual ESM + CJS (#17)

pnpm · tsdown (dual ESM + CJS) · Vitest · Biome · TypeScript 7 · shared CI from
`tselect-npm/.github@v1`. Fifth repo through the modernization runbook, after `url`
(the pilot), `thrown`, `http-method` and `schema`.

The branch's gitmoji series, which the squash would otherwise discard:

    :bug:                 Stop shipping a 1.35 MB stray log in the published package
    :wrench:              Migrate to pnpm
    :sparkles:            Add dual ESM + CJS build via tsdown, on TypeScript 7
    :white_check_mark:    Migrate test suite to Vitest
    :rotating_light:      Replace TSLint with Biome
    :memo:                Add LICENSE, a full README API section and correct metadata
    :construction_worker: Run CI from the org-wide reusable workflow

Headline fix: `@tselect/status-code@1.0.2` shipped 32 files and 1,369,746 bytes
unpacked, of which 1,352,289 were a stray `.log22069` from a 2023 test run, plus
`tslint.json`. The `.gitignore` had `.log*`, so the file was invisible to `git status`
while npm included it in every publish. Cause was `.npmignore` — a denylist cannot
enumerate files that did not exist when it was written — replaced with
`"files": ["dist"]`. Now 9 files and 7,970 bytes. `prepare: "tsc"` was also a silent
no-op under `noEmit: true`, so a clean checkout would have packed an empty `dist/`.

BREAKING CHANGE: three independent breaks.

* `engines.node` is now `">=22"`, the bottom of the CI matrix, so the floor is tested
  by construction. `>=20` is not viable regardless: pnpm 11 requires `node >=22.13`.
* The `exports` map closes deep imports. No public consumers of
  `@tselect/status-code/dist` exist.
* `isStatusCode(value: any)` becomes `isStatusCode(value: unknown)`. A widening, so no
  existing call stops compiling, but a public signature change.
