/**
 * Issue #4139: Compact Content mode — workflow.compact_content config key
 *
 * Verifies:
 *   1. config-set workflow.compact_content true → exits success, persisted as
 *      the boolean `true` (not the string "true").
 *   2. config-set workflow.compact_content false → exits success, persisted
 *      as the boolean `false`.
 *   3. config-set workflow.compact_content banana → exits failure, message
 *      matches /boolean|true|false/i.
 *   4. config-set workflow.compact_content "" → exits failure.
 *   5. config-get workflow.compact_content --raw before any set → exits
 *      non-zero (so the documented `|| echo "false"` shell fallback resolves
 *      to the literal `false`).
 *   6. Setting true twice → .planning/config.json content is identical to
 *      the single-set result (idempotency).
 *   7. Setting the key preserves every other pre-existing key/value in
 *      .planning/config.json (ordering/preservation).
 *   8. VALID_CONFIG_KEYS (msd-core/bin/lib/config-schema.cjs) has
 *      'workflow.compact_content'.
 *   9. config-new-project omitting compact_content from its workflow object
 *      still materializes workflow.compact_content === false in
 *      .planning/config.json (CONF-01 fallback default,
 *      buildNewProjectConfig's hardcoded workflow object).
 *   10. config-new-project with an explicit compact_content: true/false
 *       persists that boolean (not a string).
 *   11. config-get workflow.compact_content --raw after config-new-project
 *       exits zero and prints the persisted value.
