* working rough draft v3

* most tests passing

* works

* search v2 conversion

* added some tags.rs v2 conversions

* Worked through warnings, unwraps, prints

* refactors

* new search test

* version files changes fixes

* redesign to revs

* removed old caches

* removed games

* fmt clippy

* merge conflicts

* fmt, prepare

* moved v2 routes over to v3

* fixes; tests passing

* project type changes

* moved files over

* fmt, clippy, prepare, etc
