`@tree-sitter-grammars/tree-sitter-zig` is an optionalDependency, so every
Zig suite gates on `isLanguageAvailable(Zig)` and the ABI load-smoke accepts
a clean load failure for an optional grammar. Both are the right contract for
a platform with no prebuild, and together they leave a hole: if the grammar
never installed on any CI runner, this PR would merge with all eight Zig
resolver suites plus the structure-phase suite reported green-by-skip, having
never executed the native Zig parser once.
Close it with the `GITNEXUS_REQUIRE_FTS` idiom already used for the FTS
suites. `GITNEXUS_REQUIRE_ZIG=1` declares "this runner has a prebuild, the
grammar MUST be here", and a missing grammar becomes a failure instead of a
skip. tree-sitter-zig@1.1.2 publishes prebuilds for {darwin,linux,win32}-
{x64,arm64}, so the flag is set on two required jobs that all run on covered
platforms: the sharded ubuntu `tests` job and the three-OS `abi-assert` job.
- test/helpers/optional-grammar.ts: the registry mapping a language to its
require-variable, plus `describeGrammarPresence`, a presence assertion that
FAILS when required-but-absent. Deliberately a separate test rather than
flipping the suites from skip to fail: a skipped suite reports success, so
only a failing test can turn "Zig never ran" into a red job.
- parser-loader-abi.test.ts: the optional exemption is revoked for a language
the environment declares required, so an ABI-broken Zig binding fails the
smoke instead of passing as a clean absence.
- optional-grammar-gate.test.ts: pins the two ways the gate could silently
never fire — reading a variable name CI does not set, or accepting a value
CI does not write.
Nothing changes for a run that leaves the variable unset: local runs and any
future prebuild-less platform still skip. Verified both directions --
`GITNEXUS_REQUIRE_ZIG=1` alone: 149 passed, 0 skipped; with
`GITNEXUS_SKIP_OPTIONAL_GRAMMARS=1` forcing the grammar away it fails 2 tests
with an actionable message; with the skip flag but no require flag it is
green-by-skip exactly as before.
Addresses the test-only blocker in the gitnexus-check review of #1432.
