Remove tshy references from:
- .gitignore (tshy directories and build files)
- .prettierignore (tshy directory)
- turbo.json (tshy input pattern)

Also updates yarn cache after dependency changes.

Changes:
- Fixed TypeScript errors by removing examples from root tsconfig
- Re-added isolatedDeclarations to ansi, external-editor, figures, and type packages
- Updated tools/setup-packages.ts to handle all workspace packages (internals/)
- Added bin field handling in publishConfig for packages with CLI binaries
- Fixed TypeScript type errors in tools/setup-packages.ts
- Re-added .tshy to .gitignore as legacy build artifacts

Addresses PR #1856 review comments.

- Don't set author, license, repository, keywords, homepage for private packages
- Don't set publishConfig for private packages
- Updated tools/setup-packages.ts to check private flag and conditionally set/remove fields

Remove @arethetypeswrong/cli dependency and attw scripts from all packages
as they're no longer needed with the tshy removal. Create separate tsconfig
for examples directory to enable ESLint parsing without TypeScript
compilation errors (examples depend on built package, not source files).

The previous commit re-added examples to the root tsconfig.json which
caused TypeScript compilation errors. Examples should use their own
separate tsconfig files and not be checked by the root compilation.

Changes:
- Remove **/examples/**/* from root tsconfig.json include array
- Add tsconfig.json for packages/external-editor/examples/
- This allows ESLint to parse example files without TypeScript errors

The examples remain as-is with their 'as const' type assertions.
