[v1.0] Add provider-neutral ecosystem integrations

[codeforester]

Goal

Improve usefulness across common production CLI environments without bloating the core package.

Scope

• Evaluate optional integrations for configuration providers, validation/schema libraries, telemetry, CI annotations, and remote diagnostics.
• Keep integrations provider-neutral and opt-in.
• Define dependency, privacy, failure, and data-redaction boundaries.
• Provide small adapters and examples rather than hard-coding a vendor.
• Measure import and runtime overhead for each extra.

Acceptance criteria

• Integration boundaries are documented and versioned.
• Core installation remains lightweight and offline-capable.
• Optional adapters fail safely and preserve local operation when unavailable.
• At least two high-value integrations have reference implementations and tests.
