/**
 * #2529 — /msd-settings-integrations: configure third-party search and review integrations.
 *
 * Covers:
 *   - Artifacts exist (command, workflow, skill stub) with correct frontmatter
 *   - Workflow references the four search API key fields
 *   - Workflow exposes review.models.{claude,codex,opencode} routing
 *   - Workflow exposes agent_skills.<agent-type> injection input
 *   - #3651: workflow states the registry-derived review.models settable rule (no
 *     dynamic-pattern claim) and enumerates exactly the registry's settable lanes
 *   - #3651: workflow prescribes the JSON array agent_skills write form (never a
 *     comma-joined string); behavioral pins for array/comma/single shapes
 *   - Masking convention (****last4) is documented in the workflow and the displayed
 *     confirmation pattern does not echo plaintext
 *   - config-set round-trips all integration keys through VALID_CONFIG_KEYS,
 *     dynamic patterns, and the federated capability registry
 *   - Config merge preserves unrelated keys
 *   - /msd:settings confirmation output mentions /msd:settings-integrations
 *   - Negative: invalid agent-type name (path traversal / special char) is rejected
 *   - Negative: malformed review.models key is rejected
 *   - Logging: plaintext API keys do not appear in any file written under .planning/
 *     by the config-set flow other than config.json itself
