Subject: [PATCH 1/2] fix(py-dsl): satisfy ruff format + lint

CI (hm run on Harmont cloud) flagged real failures in the harmont-py DSL:
- ruff format: _bun.py and _toolchain.py had multi-line string concatenations
  that fit on one line; reformat them.
- ruff check (E402): tests/test_bun.py imported pytest + harmont mid-file
  (after the first test batch). Hoist both to the module's import block.

ruff format --check, ruff check, ty, and pytest (404 passed) all green.

Subject: [PATCH 2/2] ci: add bun to the examples matrix

examples/bun exists on disk but was missing from the example: matrix in
examples.yml, so the validate-matrix guard failed. Add it.
