Follow-up to #26 / issue #25.

PR B

• Removed TemplateGenerator.listTemplateFiles()
• CLI --list calls adapters/list-files + markup-generator.pathExists
• Engine lists catalog ids via ids()
• Tests for directory scan live in adapters/list-files.test.ts

PR C

• src/render.ts no longer imports fs or the spawn adapter
• File entries only work when generator injects fileRenderer (allowFileTemplates: true)
• Spawn + temp files moved to src/adapters/file-renderer.ts
• Deleted src/render/file-adapter.ts

rg node:fs src/generator.ts src/render.ts should be empty.
node:fs / spawnSync remain in src/adapters/file-renderer.ts (temp payload + child process) and src/cli.ts no longer uses node:fs.
