Subject: [PATCH] Anchor project-only patterns in .mcpbignore template
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Unanchored gitignore patterns (no leading `/`) match anywhere in the
tree — including inside `deps/`. Patterns like `tests/`, `docs/`, or
`conftest.py` end up stripping legitimate runtime files from vendored
dependencies, breaking imports when the bundle starts.

Split the template into two sections:
  1. Strip anywhere (`__pycache__`, `*.pyc`, `.DS_Store`) — safe
     cross-tree hygiene.
  2. Project-only (anchored with `/`) — patterns that must only match
     at the project root.

Also drops `conftest.py` (redundant with `/tests/`, and collides with
legitimate runtime modules like `beartype._conf.conftest`).
