/**
 * Trello MCP transport — implements the @llodev/pm-tasks-core Transport
 * interface by dispatching every canonical verb through `mcp__trello__*`
 * tool calls. The MCP dispatcher is injected (caller-supplied callback,
 * matching the established `probeMCP` pattern in
 * pm-tasks-core/src/init-lib.ts) so this module stays:
 *
 *   - testable           — tests inject a recording stub
 *   - side-effect free   — `import` does not throw, log, or call anything
 *   - decoupled at build — no `mcp__*` symbols are referenced at compile time
 *
 * Verb mappings follow `pm-tasks-trello/references/operations.md` verbatim.
 * Idempotency fetches stay at the handler / Phase 5 hook layer per the
 * Phase 2 contract; this transport is a thin dispatcher that classifies
 * MCP errors into TransportErrorCode and wraps each result in a typed
 * TransportResult<T> envelope.
