Move authentication-mode resolution into typed config parsing with ConfigUserAuth,
so downstream login setup consumes validated credentials instead of re-checking raw optional fields.
Enforce explicit password-vs-token selection, validate token/device/user-id requirements in one place,
and normalize empty auth env overrides to unset values for consistent behavior across YAML and environment input.
- Add mise.toml (prek 0.3.2) and .pre-commit-config.yaml with hooks for
trailing whitespace, end-of-file, YAML check, merge conflicts, large files,
cargo fmt, cargo clippy (-D warnings), and unit tests
- Add prek/mise recipes to justfile
- Run cargo fmt to fix formatting issues
- Fix all clippy warnings: collapse nested if statements, derive Default for Avatar
This is based on the work done in https://github.com/etkecc/baibot/pull/60 by https://github.com/Fmstrat (Ben Curtis),
with various changes on top to make the code more idiomatic and flexible.
This commit squashes the following patches (newest first):
- Improve handling of `user.avatar` configuration (null & empty string being the same now) and add support for a special `keep` value
- Minor import reordering
- Simplify avatar configuration (`user.avatar.source` -> `user.avatar`)
- Combine `logo_bytes` and `mime_type` determination logic and do not fall back to default avatar if reading the custom avatar file fails
- Switch from deprecated `mime_guess::guess_mime_type(avatar_path)` to `mime_guess::from_path(avatar_path).first_or_octet_stream()`
- Relax `mime_guess` constraint and order alphabetically
- Use `mime` from `mxlink`
- Add mime-type support and switch to user.avatar.source
- (Original work by Fmstrat) Add support for custom avatars
