cldk-devtools v0.2.0 — the CLDK mode ladder

cldk-forge is now cldk-devtools: a superpowers-style mode ladder for developing
and maintaining CodeLLM-DevKit.

Breaking

• Plugin renamed: install is now /plugin marketplace add codellm-devkit/cldk-devtools
  • /plugin install cldk-devtools@codellm-devkit (old URLs redirect).
• Skill prefixes change: cldk-forge:* → cldk-devtools:*.

The ladder

• using-cldk-devtools — session dispatcher, injected only inside CLDK repos.
• designing-cldk-changes — contract-impact triage, design loops, spec → epic.
• maintaining-cldk — triage → contract gate → fix loop → propagation sweep.
• codeanalyzer-backend — analyzer rung, rewritten (levels L1–L4, per-level guides).
• cldk-sdk-frontend — SDK rung, rewritten (two-layer model, per-SDK wiring).
• finishing-cldk-work — verification gates, releases, closeout.

Every skill authored test-first with subagent scenarios (see tests/).
