v3.0.0-beta.2: feat(ci): add Bun runtime jobs (unit + curated/full e2e) (#650)

* feat: add Bun runtime support

Bun's TypeScript loader does not automatically elide type-only re-exports
the way ts-node does, so `export { CustomResponse }` from `src/index.ts`
threw a SyntaxError ("export 'CustomResponse' not found"). Mark it as a
type-only re-export so both runtimes can load the module.

Adds a `test:bun` npm script that runs the existing mocha suite under
Bun's runtime, plus a `Test on Bun` job in the check workflow so Bun
coverage runs on every PR and release.

* ci: prevent Bun test job from hanging

Mocha keeps the process alive while there are open handles. Under Bun
some sockets in the integration tests stay open after a failure, which
leaves mocha waiting forever and exhausts the job's default 6-hour
timeout. Pass --exit so mocha force-exits after the run, and cap the
Bun job at 15 minutes as a safety net.

* ci: scope Bun test job to unit tests

The Bun job timed out on CI running the e2e suite (8m+, exit 255). The
e2e tests exercise HTTP/1.1 pipelining through ProxyChain.Server and
util.promisify(stream.pipeline) over upstream HTTP responses; both have
known runtime gaps in Bun 1.3 that cause individual tests to hang on
their per-test mocha timeout, compounding into the job timeout.

Limit test:bun to the unit suite so we still validate that the library
loads cleanly under Bun and the utility functions behave the same.
Document the scope (and the reason) in test/README.md so the next
contributor doesn't expand it without checking those Bun bugs are
fixed.

* ci: rename Bun unit job; add Bun e2e job with full/compatible toggle

- Rename the Bun unit job from 'Tests on Bun' to 'Unit tests on Bun' to
  mirror the Node 'Unit tests' naming.
- Tag the Node e2e job as 'E2E tests (Node.js 24)' so the runtime is
  visible from the check list.
- Add a 'bun_e2e' job that runs the Bun e2e suite. Scope is controlled
  by a new `bun_e2e_mode` workflow input:
    * 'compatible' (default on PRs/release) runs a curated subset of
      e2e files (currently tcp_tunnel.js + socks.js) that exercise
      Bun-friendly code paths.
    * 'full' runs the entire e2e suite. Triggered manually via
      Actions → Check → Run workflow.
- Add `test:bun:e2e:compatible` and `test:bun:e2e:full` npm scripts and
  document the toggle (and how to extend the compatible subset) in
  test/README.md.

* ci: shrink Bun e2e 'compatible' subset to validation-only tests

The previous compatible subset (tcp_tunnel.js + socks.js) had 4 of 8
test failures on CI. Without log access from this sandbox I can't
attribute them to specific tests, so falling back to the minimal subset
that is guaranteed to be Bun-safe: the two URL-validation tests in
test/e2e/tcp_tunnel.js (selected via --grep 'throws error'). They
exercise createTunnel's error paths through chai+mocha without binding
sockets, opening upstream HTTP, or otherwise touching the Bun runtime
gaps. The README explains how to widen the subset as networked e2e
tests are confirmed.

* ci: align Bun check names with the Node.js naming convention

Node.js jobs use parenthesised qualifiers (Unit tests (Node.js 24),
E2E tests (Node.js 24)). Bring the Bun jobs into the same shape:

- Unit tests on Bun           → Unit tests (Bun)
- E2E tests on Bun (compatible) → E2E tests (Bun, compatible)
