Add the following tickets:

Read @docs @src @tests @PLAN.md @README.md and @CLAUDE.md for context.

* Add a `--filter` flag to `list`, `ready`, and `migrate` commands.
    * This should accept `key=value` pairs for all metadata.
    * Keys include: priority, type, status, title.
    * Users can pass multiple key=value pairs.
    * When passing different keys this is a logical AND reducing the results.
    * When passing the same key with different values, this results in a logical OR expanding the results.
    * Values should support globs,
      * Example: `status=*` matches all status values
      * Example: `--title=*command*` matches all tickets with 'command' in the title

* By default do not include `done` tasks in `nbd list`. Require `--filter status=*` or `--filter status=done`

* Add a new `next` subcommand which chooses the highest priority ticket which is ready to be worked on.
    * This should support the `--filter` flag.

Deeply understand each item before planning.
Create `nbd` tickets for each item including your plan, breaking the problem down into smaller tickets where it makes sense.
Include relevant source files, documentation, and context about each ticket so the work has the higest probability of success without additional context being required.
Do not implement any tickets.
