v0.1.1 | Symmetric selection

What's new:

• Symmetric part selection: picking a part that has symmetry counterparts (e.g. one of 4 landing legs placed with 4x symmetry) now selects and assigns the whole group at once. Hover during "+ Part" previews the entire group in cyan, the persistent selection highlights all of them in blue, and the window shows a single card for the group instead of one row per physical part.
• Action picker hides already-assigned actions: the "+ Action" list no longer offers an action that's already assigned to the selected part for the current group and set.
