feat(integrations): load bundle capability manifests

[erichare]

Summary

• Add optional, bundle-owned integration capability manifest references to the extension schema.
• Validate versioned provider metadata covering actions, authentication, required scopes, policy keys, execution substrate, maturity, and deployment contexts.
• Expose validated capabilities through both extension load results and the process-wide bundle registry.
• Document the authoring contract while preserving compatibility with extension manifests that omit integrations.

Stacked on #14919.

Compatibility and safety

• Existing extension manifests continue to load with an empty integrations collection.
• Capability paths must be relative JSON paths contained by the owning bundle.
• Provider IDs must match between the extension reference and capability document.
• Capability validation runs before model-provider registration side effects.

Validation

• 699 passed — lfx integration and extension test suites
• 36 passed — capability-matrix CI test suite
• Ruff checks passed
• Extension schema export passed
• Capability-matrix completeness check passed
• Bundle API changelog gate and commit hooks passed
• scripts/ci/sync_bundle_lfx_pin.py 1.13.0 completed without a diff because existing bundle floors already use the canonical constraint
