Amber Code Review — LGTM

Routine automated version bump: anthropic 0.103.1 → 0.104.1, claude-agent-sdk 0.2.82 → 0.2.87. Changes are limited to pyproject.toml (version constraints) and uv.lock (locked hashes). Hash values in the lockfile match the PyPI upload URLs. No behavioral changes, no API surface changes, no convention issues.

Per amber-config.yml auto_fix.categories.Dependency Patches: patch-level and minor SDK bumps of this kind are low-risk and routine. require_ci_pass: true — CI should be verified before merge.

No blockers. No criticals. Merge when CI is green.
