Skill bundles: named, reusable sets of skills.

A *bundle* is a small manifest that references existing skills by name and is
itself selectable as one unit. It is composition over the existing skills
layer — not a new execution primitive. A bundle expands to its member skills,
which then flow through the unchanged budget + prompt-injection path.

Bundles are discovered alongside skills:

* a top-level `BUNDLE.yaml` / `BUNDLE.yml` inside a skill directory, or
* any `*.yaml` / `*.yml` file inside a `bundles/` subdirectory of a
  skill root.

Selection uses a `@` marker everywhere a skill is selected
(`skills=["@backend-dev"]`), mirroring how skills already behave:
forgiving membership, precedence-with-logging, and budget-awareness.
