/**
 * AgentBBS MCP Tools — Federated business-domain BBS room surface (ADR-164 Phase 1).
 *
 * Exposes the `agentbbs@~0.1.0` (a sibling BBS-style federation peer by the same
 * author as ruflo) as MCP tools so ruflo agents can register business rooms
 * (#sales, #finance, #marketing, ...), publish/watch typed envelopes, and
 * mint single-use human-join tokens for SSH/web cockpit access.
 *
 * Motivation:
 *   ADR-164 wires the "business autopilot" cockpit on top of the existing
 *   ruflo federation primitives (FederationEnvelope, PII pipeline, budget
 *   circuit breaker). The 4 tools here are the ruflo-side handles into the
 *   agentbbs Rust workspace (`crates/agentbbs-federation/` and
 *   `crates/agentbbs-mcp/`) that already implement Ed25519-signed envelopes
 *   and an MCP transport. Phase 1 ships the surface; Phases 2-5 wire deeper.
 *
 * Architectural constraint (mirrors metaharness-tools.ts / agenticow-tools.ts):
 *   - `agentbbs` lives in `optionalDependencies` — must NOT be a hard runtime dep
 *   - When the package is missing, every tool returns
 *     `{success: true, degraded: true, reason: 'agentbbs-not-found'}`
 *     so callers see one contract regardless of install state
 *   - Phase 1: polling-based watch (streaming subscriptions are Phase 4)
 *
 * Presence check: the published `agentbbs` package (as of 0.2.1) is a CLI-only
 * launcher — a `bin` script with no importable JS entry point (no `main` /
 * `exports` field) — that downloads/builds a Rust binary and shells out to it.
 * `await import('agentbbs')` can therefore never resolve, even when the CLI is
 * correctly installed and on PATH: there is no module for Node to find. This
 * previously made every tool report `degraded: true` unconditionally,
 * regardless of install state. Detect real availability instead by probing the
 * CLI itself, matching how the rest of this codebase treats optional
 * command-line tools (`shutil.which()`-style guards) rather than assuming a
 * package shape the dependency doesn't have.
 *
