Centralize repository workflows and VS Code configuration

[artiphishle]

Summary

Implements #24.

• reorganizes Devtools concerns under src/tools/
• adds canonical GitHub Actions workflow assets
• adds canonical VS Code settings and extension recommendations
• adds ankh devtools sync and ankh devtools status
• adds scoped workflow and VS Code sync/status commands
• supports deterministic idempotent synchronization and --dry-run
• adds the required bunx @ankhorage/ankh doctor validate . CI step
• packages managed assets into dist
• updates provider metadata, documentation, and tests
• removes the old architectural assignment to @ankhorage/dev

Command surface

ankh devtools sync [path]
ankh devtools status [path]
ankh devtools workflows sync [path]
ankh devtools workflows status [path]
ankh devtools vscode sync [path]
ankh devtools vscode status [path]

Sync commands support --dry-run.

Validation

The local implementation checks are green, including build, typecheck, lint, Knip, and tests.

Architecture

The concerns are equal siblings under src/tools:

src/
├── cli/
└── tools/
    ├── eslint/
    ├── prettier/
    ├── knip/
    ├── workflows/
    ├── vscode/
    └── shared/

There is deliberately no generic templates/ layer.

Compatibility

No legacy aliases, migration shims, deprecation wrappers, or ankh dev ... compatibility surface are included. The only canonical command prefix is ankh devtools ....

Closes #24.
