Add `Status::Closed` (serialised as `"closed"`) and a convenience `nbd archive <id>` command that sets it.

## Motivation

`done` tickets clutter `nbd list`. `closed` provides a soft-delete: the ticket is preserved on disk but excluded from normal listings by default.

## Approach

### ticket.rs
- Add `Closed` variant to `Status` enum (after `Done`).
- `#[serde(rename_all = "snake_case")]` already handles serialisation → `"closed"`.

### main.rs
- Update `parse_status` to accept `"closed"`.
- Update `status_str` in `display.rs` to map `Status::Closed` → `"closed"`.
- Add `Archive` variant to `Commands`:
  ```
  Archive { id: String }
  ```
- Implement `cmd_archive(id, json)`: read ticket → set status to `Closed` → write → print.
  This is syntactic sugar for `nbd update <id> --status closed`.

### display.rs
- Add `"closed"` to `status_str` match arm.

### list filtering
- `nbd list` currently shows all tickets. After this change, it should by default **hide** `Closed` tickets.
- Add a `--all` flag to `nbd list` to show all tickets including closed ones.
- Update `list_tickets` or filter at the command handler level. Prefer filtering in `cmd_list` to keep `list_tickets` generic.

## Tests
- Unit test: `Status::Closed` serialises to `"closed"` and back.
- Integration test: `nbd archive <id>` sets status to `closed`.
- Integration test: `nbd list` does not show closed tickets.
- Integration test: `nbd list --all` shows closed tickets.
