chore: reconcile Bootstrap manifest contract

[jmcte]

Summary

• Reconcile the project manifest with the current Bootstrap schema and safety contract.
• Declare the repository's CodeQL language/build targets, canonical class migration, or managed-path dependencies as applicable.

Governing Issue

No governing issue is linked; this is a scheduled Bootstrap fleet reconciliation.

Validation

• The repaired Bootstrap control plane produced a plan for this manifest without schema or ownership-validation errors.
• The change is limited to project.bootstrap.yaml.

Bootstrap Governance

• No real secrets, runtime auth, or machine-local environment files are committed.
• Existing local worktrees were preserved; this PR was created from refreshed origin/main.

Merge Automation

Auto-merge is not available until a maintainer reviews and enables it for this scheduled reconciliation PR; fallback merge-readiness applies.

Notes

• This PR is intentionally manifest-only. Bootstrap-managed generated files should be applied only after this manifest contract is reviewed and merged.

Request changes: the claimed Bootstrap validation is not reproducible at this head. Running node /openclaw-data/src/omt-global/bootstrap/dist/cli.js plan --manifest ./project.bootstrap.yaml --target . fails because archetype.packageManager: swift is unsupported; the accepted values are npm, pnpm, yarn, and python. Please make this a valid current Bootstrap contract (use a supported generic-empty value, or first land/use Bootstrap support for Swift) and rerun the plan. Also reconcile the newly declared ci.codeqlLanguages with a supported Bootstrap schema/generator—the current schema has no such field—and update docs/bootstrap/onboarding.md, which still identifies the repo as generic-polyglot while this PR changes it to generic-empty. CI is green, there are no prior reviews or review threads, and the branch merges cleanly, but the control-plane validation blocker prevents approval.

Approved. Reviewed live head 733347c42c66e547a1329a17025a83375e4e1bea in a detached Athena-node worktree. With the Bootstrap revision cited by the PR (3ae5bba9858437663eb171b6f18a52075182d38b), the plan accepts generic-empty with Swift and ci.codeqlLanguages, and reports the changed onboarding document and pre-commit hook unchanged. npm run typecheck, npm test, and a no-staged-files pre-commit-hook smoke test passed. Live PR Checks and CI Gate succeeded; Trusted Checks is expectedly skipped for a pull-request event. The branch is clean/mergeable, and no review comments or conversation comments were present.
