feat(mcp): add gittensory_validate_config tool for .gittensory.yml

[RealDiligent]

Summary

Adds gittensory_validate_config so contributors/operators can pre-validate a .gittensory.yml string before pushing. The tool uses parseFocusManifestContent as the single parser source and returns { present, warnings, normalized, status } where status is ok | warn | error.

Surfaces:

• Hosted Worker MCP (src/mcp/server.ts)
• stdio MCP package (packages/gittensory-mcp/bin/gittensory-mcp.js)
• API route POST /v1/validate/focus-manifest
• CLI gittensory-mcp validate-config --file <path>

Private maintainerNotes are omitted from normalized output.

Closes #2057

Validation

npm test -- test/unit/focus-manifest-validation.test.ts test/unit/mcp-output-schemas.test.ts test/unit/mcp-cli-validate-config.test.ts
npm run build --workspace @jsonbored/gittensory-engine
npm test -- test/unit/mcp-output-schemas.test.ts -t gittensory_validate_config

• test/unit/focus-manifest-validation.test.ts — ok/warn/error arms, malformed YAML/JSON, oversize input, maintainerNotes redaction
• test/unit/mcp-output-schemas.test.ts — hosted MCP tool + outputSchema
• test/unit/mcp-cli-validate-config.test.ts — CLI wrapper
• test/integration/api.test.ts — API route happy/invalid paths

• Public audience mode: oss maintainer
• Lane context: Repository is configured for direct PR review.

Contributor next steps

• Keep the PR focused and include validation evidence before maintainer review.

Signal definitions

• Related work = same linked issue, overlapping active PRs, or title/path similarity.
• Change scope = cached public metadata such as size labels, draft state, and review-burden hints.
• Validation posture = whether the PR provides enough public validation/test evidence for maintainer review.
• Contributor workload = public contributor activity and cleanup pressure, not a repo-wide quality failure.
• Contributor context = public GitHub/Gittensor identity context; non-Gittensor status is not a blocker.
