/**
 * `agent-bober blackboard publish|read` — inter-agent fleet blackboard CLI (Phase B).
 *
 * Subcommands:
 *   publish <value> [--round N]  — Publish a finding to the shared fleet blackboard.
 *   read [--all]                 — Print findings from the shared fleet blackboard.
 *
 * Error handling: CLI handlers MUST NOT throw. They set process.exitCode=1 and
 * return on all errors. Pattern mirrors src/cli/commands/facts.ts.
 *
 * The db path is read from config.fleet.blackboardDbPath ONLY — never re-derived
 * from cwd. This is the child-visible seam: the scaffolder wrote the absolute path
 * into each child's bober.config.json so children in different cwds can share one db.
