Fix Namor, Atlantean King - #7493

Scan completed across all four areas:

1. CI/CD — No GitHub Actions workflow files or CI configuration changes present.
2. Lifecycle — No package-manager hooks (preinstall, postinstall, prepare, etc.), no Cargo build.rs, no Docker entrypoints, no git hooks changed.
3. Malicious intent — All 31 changed files are Rust source code in a Magic: The Gathering game engine (*.rs). The changes add parser support for card-text predicates ("who has more life than you", "attacking that player") and a new TargetFilter::PlayerMatching enum variant. No network calls, secret exfiltration, obfuscation, encoded payloads, credential handling changes, telemetry, suspicious binaries, or dangerous eval/exec patterns were found. The extensive CR (Comprehensive Rules) references, revert-failing tests, and mechanical signature updates across the engine and AI policy crates are consistent with a legitimate parser-fidelity bugfix.
4. Skill mutations — No materialized skill target directories to scan.

All verification gates in the PR description passed (tests, clippy, coverage, semantic-audit).
