helix-fusion-invariants-lint-56-skills-intentionally-out-of-scope

The fusion-invariants-lint.py ORCHESTRATORS list tracks 71 of 127 on-disk skills. The 56 unlisted skills are intentionally excluded and fall into four categories: platform SMEs (salesforce, snowflake, etc.), framework/infra utilities (setup-curator, vault, serena), tooling skills (playwright-cli, ast-grep), and project-specific skills (runwal-bkc-website, joggai). A comment block was added to the lint script explaining this to prevent future confusion about apparent undercoverage.
