M0.1: enforce the asset rule in CI (cargo xtask assets); replace Adobe-published Source Sans 3 with Inter

Every image/icon/font/media/profile file must match an assets/ATTRIBUTION.md path pattern;
Adobe profile/template formats and Adobe-named assets are rejected.

Every asset shipped in this repository is listed here (see the asset rules in `AGENTS.md`). No asset may come from
Adobe products. Add an entry in the same commit as the asset.
`cargo xtask assets` (part of `cargo xtask ci`) fails if any image, icon, font, sound, video, raw file or colour profile
in the repository is not matched by a path pattern in the first column (`*` = any characters except `/`; a trailing `/`
covers a whole directory), or if a licence file referenced in the Licence column is missing.

Notes
- Source Sans 3 is an open-source (OFL) typeface; it is used as a general-purpose UI font. It is distributed under the
OFL and is not an asset taken from any Adobe application.
- Fonts authored or published by Adobe (Source Sans/Serif/Code, Source Han, …) are not used, even though some are
OFL-licensed: the asset rule excludes anything from Adobe. Source Sans 3 was removed on 2026-09-30 and replaced by Inter.
