Add Support for CMake Presets Version 11

[hanniavalera]

Summary

Adds support for CMake Presets version 11, introduced in CMake 4.3. The only schema change from v10 is that execution.jobs in test presets can now be an empty string, equivalent to passing --parallel with no value (letting CTest auto-detect the job count).

Changes

Schema & validation

• New CMakePresets-v11-schema.json - copy of the v10 schema with testPresets.execution.jobs widened to accept either an integer or an empty string (anyOf [integer, string with maxLength: 0]).
• presetsParser.ts - bumped maxSupportedVersion from 10 → 11; added explicit v10 routing so the v11+ fallthrough uses the new schema.
• package.json - updated jsonValidation entries for CMakePresets.json and CMakeUserPresets.json to reference the v11 schema.

Runtime behavior

• preset.ts - testArgs(): when execution.jobs is an empty string, pushes only --parallel (no value). When it's a number, behavior is unchanged (--parallel <N>).

Tests

• validation.test.ts - added two new test cases:
  • v10: validates that graphviz (added in v10) is accepted on v10 and rejected on v9.
  • v11: validates that an empty-string execution.jobs is accepted on v11 and rejected on v10.

Docs

• cmake-presets.md - updated supported version range to "version 2 through 11".
• CHANGELOG.md - added entry under Features.

Testing

• yarn run compile - clean build, no errors.
• npx tsc -p test.tsconfig.json --noEmit - test project type-checks cleanly.
• New validation tests cover both the accept and reject paths for v10 and v11 schema changes.
