feat(testing): built-in test blocks + expect assertions, auto-run with pass/fail (#12)
A `test "name" { ... }` top-level block is discovered automatically and run by a
synthetic runner @main — no `entry` to write, nothing to register. Inside a test,
expect(cond) / expect_eq(a, b) / expect_near(a, b, tol) assert; on failure they
print `file:line: <what> failed (got G, want W)` and set a per-test fail flag but
keep going, so one run reports every failure. The runner prints `ok   - name` /
`FAIL - name` per test, a `== N passed, M failed ==` summary, and exits non-zero
if any test failed — so `ludic spec_test.ludic` drops straight into bin/x and CI.
expect_near carries the tolerance fixed-point / accumulated-integer game math need.

Frontend: new `test` keyword (parse_test -> N_TEST, collected in g_tests) and the
call node now carries its source line for the file:line messages. Backend:
emit_test_runner synthesises @fn__test_i bodies + the runner @main; the expect*
builtins lower to a branch-print-flag tail (emit_expect_fail). g_src_name (set in
main from the input path) supplies the filename. The compiler's own source has no
`test` blocks, so its self-compiled IR is unchanged and the C-free fixpoint holds.

- `test` wired into the vocabulary (ludic_syntax.h, JetBrains lexer, TextMate
  grammar) and documented (docs/language/testing/)
- examples/library/testing.ludic: a passing spec, guarded by a new spec_case in
  the regression suite (build, run, require exit 0 + the expected summary)

Coverage instrumentation (the biggest lift in #12) is left as a follow-up.

bump: minor type: feat Built-in testing framework — a test "name" { … } block, discovered and run automatically by a synthetic runner (no entry to write). Inside a test, expect(cond), expect_eq(a, b) and expect_near(a, b, tol) assert; on failure they print file:line: … failed (got …, want …) and mark the test failed without aborting, so one run reports every failure. The runner prints ok - name / FAIL - name per test, a == N passed, M failed == summary, and exits non-zero if any test failed — so ludic spec_test.ludic drops straight into bin/x and CI. expect_near carries the tolerance fixed-point and accumulated-integer game math need. Coverage instrumentation is a follow-up.
