chore(eslint): fix pre-existing errors surfaced by wider .cjs match

- Widen config match from top-level *.cjs to **/*.cjs so nested CommonJS
  scripts (e.g. mcp-schema-server.cjs) get Node globals and require() allowance.
- Replace lazy require() in claude-skills.ts with a normal top-level fs import.
- Tighten an any-typed tool map in pi-claude-cli to { name: string }.

Clears the remaining 12 lint errors; workspace now has 0 errors, 450 warnings.
