Summary

Brings gts-dotnet in line with gts-spec v0.17.0. The full spec suite passes: ./gts.sh gts-dotnet gives 2367 passed, 0 failed.

• Pattern engine (§10): new GtsPattern handles identifier matching and coverage. It is used for ID validation (OP#1), parsing (OP#3), matching (OP#4) and query wildcards. Versions are unsigned 32-bit and a single-segment instance ID is rejected.
• Regex profile (§11.0.1, ADR-0006): expressions are checked against the profile everywhere they appear, including targets reached only through $ref. They are translated to reference semantics (code-point atoms, ASCII \d \w \s, $ matching end of input) and run on the linear-time non-backtracking engine, replacing the 250 ms timeout. additionalProperties no longer recompiles patternProperties with the ECMAScript engine, which rejected astral ranges.
• Reference keywords (§9.6): x-gts-type-ref, x-gts-instance-ref and x-gts-pattern-ref replace x-gts-ref, which is now rejected as an unknown keyword (breaking). Derivation and evolution checks now cover references by testing semantic scope inclusion.
• Hardening:
  • Inlining stops at 100,000 nodes, so shared refs cannot blow up exponentially.
  • Literal data (const, enum, default, examples) is left unchanged.
  • A local ref inside an inlined document resolves against that document.
  • A not containing a reference keyword also checks its structural part, so values of another type are no longer wrongly rejected.
  • Every level of a recursive schema is checked.
  • /$id accepts unsigned 32-bit versions.

Stacked on #4 (CI workflow); retarget to main once #4 merges.

Test plan

• dotnet test (165 existing tests plus 5 new ones in ReferenceResolutionHardeningTests)
• dotnet format whitespace|style --verify-no-changes
• ./gts.sh gts-dotnet against gts-spec v0.17.0: 2367 passed
