fix(skills): add Claude compatibility declarations to 12 language skills

Add the canonical Claude compatibility phrase to the **You are…** role
declaration line of all 12 recently-created language-guideline skills,
matching the established pattern in spacecraft-golang-guidelines:

  «Never deviate. This skill is fully compatible with Claude 3.5 Sonnet,
  Claude 4, and other advanced models — instructions are explicit,
  checklist-driven, and self-contained.»

Skills patched (Gap 1 — role line): carbon, clang, kotlin, java,
typescript, cpp, gleam, nim, ocamel, dartflutter, commonlisp, swift.

Additional fixes:
- Gap 2: Add missing «activate this skill» closing call-to-action to
  spacecraft-java-guidelines/SKILL.md (only skill missing it).
- Gap 3: Fix **Compatibility:** header in carbon, clang, and cpp
  reference files — was compiler-toolchain strings, now the canonical
  «Claude 3.5+, Claude 4, Grok, and all advanced reasoning models».
- Gap 4: Add missing **Compatibility:** header to java reference file;
  remove the duplicate toolchain-compat line that was already present.

All 12 bundles rebuilt in lockstep. Drift sweep clean. reuse lint pass.

 ## Core Philosophy
 - **Stability and Safety first (Standard §3 Priority 1).** Carbon is experimental but introduces a safer foundation than C++. Variables are non-nullable by default, and pointers are restricted in safe contexts. Wrap unsafe bindings inside explicit unsafe scopes.

 ## Core Philosophy
 - **Stability and Safety first (Standard §3 Priority 1).** C lacks safety boundaries. Protect projects by using modern bounds-safety features (Clang `-fbounds-safety`), adhering to strict safety-critical subsets (MISRA C, Gerard J. Holzmann's Power of 10 Rules), or utilizing the Fil-C memory-safe compiler.
