* refactor(ui): build every dropdown on craft_ui::ComboBox
Repin craft-libs to the revision with craft_ui::ComboBox, whose menu grows back
after its contents shrink while it is open (egui#5225), and ban egui::ComboBox
in clippy.toml.
* fix(type): the font menu grows back after a search
The search field is the ComboBox header and only the family list scrolls, so
the menu follows the list's height: no unfiltered height kept while searching.
* chore(deps): craft-libs 60d60d48 (dropdown fixes)
* chore(deps): craft-libs 6af63481 (dropdown fixes)
* chore(deps): craft-libs 4d7b82f7 (dropdown fixes)
* chore(deps): craft-libs 92d392cf (#387 merged)
AGENTS.md gets a prominent "Never crash" section at the top of the golden
rules (Rule 9 now points to it), docs/contributing.md a short paragraph,
a root clippy.toml lets tests use unwrap/expect/panic/indexing, and the
workspace moves unsafe_code from "deny" to "forbid" (no unsafe exists in
the workspace).
