+++ title = "nbd init command" priority = 7 status = "done" ticket_type = "feature" dependencies = [] +++ Add an explicit nbd init subcommand that creates .nbd/tickets/ in the current working directory, analogous to git init.

Motivation

Currently users must run mkdir -p .nbd/tickets manually before first use. This is a friction point — especially for first-time users and agent workflows bootstrapping a new project.

Approach

1. Add Init variant to the Commands enum in main.rs.
2. Implement cmd_init(json: bool) -> store::Result<()>:
   • Get cwd via std::env::current_dir().
   • Call store::ensure_tickets_dir(&cwd) (already exists, idempotent).
   • Print confirmation: initialised .nbd/tickets/ in <path> (or JSON: {"root": "<path>"}).
3. No changes to store.rs needed — ensure_tickets_dir already uses create_dir_all (idempotent).
4. The command should NOT require .nbd/ to already exist (i.e. do NOT call find_nbd_root here — use cwd directly).

Tests

• Integration test: run nbd init in a fresh tempdir, verify .nbd/tickets/ is created.
• Integration test: run nbd init twice in the same dir — succeeds both times (idempotent).
• Integration test: nbd init --json outputs valid JSON with a root field.

Files touched

• src/main.rs — new Init variant and cmd_init handler
• tests/integration.rs — new integration tests
• README.md — update Initialise section
