Connect Echodo to itself: Cursor sessions can now call this repo's MCP
server (`claim_task`, `complete_task`) over stdio, and operators can
bootstrap the DB from `plans/` without leaving a long-running file
watcher in place.
- `.cursor/mcp.json`: register `echodo` MCP server. Spawns
`pnpm -s --filter @tasks/mcp-server mcp`. The `mcp` script invokes tsx
with `--env-file=../../.env` so DATABASE_URL is picked up at the
per-session process boundary without leaking into committed config.
- `import:markdown-backlog`: new one-shot importer (sibling of the
existing watch script). Until the DB → markdown export side lands
(see follow-up task), running the watcher continuously would clobber
agent-driven status flips on every sweep. The one-shot variant runs a
single `syncMarkdownBacklogScan` pass and exits.
- File `Task-export-db-to-markdown-frontmatter.md` documenting the
remaining direction of the sync loop.
Smoke-tested end-to-end against the homelab DB: full `claim_task` →
`complete_task` round-trip via real MCP stdio protocol, with agent_runs
+ audit_log rows landing as expected and the backlog item status
restored via `finalStatus`.
