In Rust, the `or` and `or_else` methods have distinct behavioral differences. The `or` method always eagerly evaluates its argument and executes any associated function calls. This can lead to unnecessary performance costs—especially in expensive operations like string processing or file handling—and may even trigger unintended side effects.
In contrast, `or_else` evaluates its closure lazily, only when necessary. Introducing a Clippy lint to disallow `or` sacrifices a bit of code simplicity but ensures predictable behavior and enforces lazy evaluation for better performance.
* perf: utilize smartstring for string handling
- Updated various modules to replace standard String with smartstring::alias::String for improved performance and memory efficiency.
- Adjusted string manipulations and conversions throughout the codebase to ensure compatibility with the new smartstring type.
- Enhanced readability and maintainability by using `.into()` for conversions where applicable.
- Ensured that all instances of string handling in configuration, logging, and network management leverage the benefits of smartstring.

- Honor Freedesktop precedence when locating mimeapps.list
- Replace per-scheme HashSet with index-tracking HashMap
- Merge duplicate handler entries instead of discarding them
- Ensure all schemes exist using the new tracking structure
- add retry path that restarts Mihomo on connection-related reload errors
- guard runtime config state by discarding on repeated failures and returning rich errors
