Don't remove this, it's for the new patcher

config_path in new patcher is the equivalent of the overlay path, we need to make the backend implementation abstract enough so that it can support the current (legacy) patcher and the new one as well.

Do not remove the new patcher hook routine implementation, instead move this code from the command file into the relevant patcher module and make it abstract at the point of calling - this file, so we support multiple patcher implementations.
…mod import - Abstract patcher backend to support both legacy and new patcher APIs - Move new patcher hook logic into patcher/runner.rs and patcher/api.rs - Move legacy patcher loop into legacy_patcher/runner.rs - Add MutexLockFailed error variant with MutexResultExt trait for cleaner mutex handling - Fix fantome extractor: case-insensitive META/info.json lookup, UTF-8 BOM handling - Add drag and drop support for mod installation in Library page - Add overlay progress events and display in Start Patcher button - Fix clippy warnings in mods/mod.rs and overlay/mod.rs Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
