Problem

.nbd/cache.db is a Turso/libsql SQLite cache file created automatically by list_tickets_cached. It should never be committed to git. Currently nbd init does not create a .gitignore to exclude it.

Implementation

src/main.rs — cmd_init

After ensure_tickets_dir succeeds, write (or append to) .nbd/.gitignore:

cache.db

Use idempotent logic: read the file if it exists, check whether cache.db is already listed, and only append/create if it is absent. This keeps nbd init safe to run multiple times.

Suggested helper (can be inline in cmd_init):

1. Read .nbd/.gitignore if it exists.
2. If cache.db is not a line in the file, append cache.db\n.
3. If the file does not exist, create it with cache.db\n.

The JSON output for --json should include a gitignore key indicating the path that was created/updated (or unchanged).

tests/integration.rs

Add a test that runs nbd init and asserts .nbd/.gitignore contains cache.db. Run nbd init a second time and assert the file is unchanged (idempotent).
