List Fallout in awesome lists

### Problem

Fallout appears in no curated "awesome" list. NUKE, the project Fallout forked from, is listed in roughly 28 list repositories. Someone looking for a C#/.NET build system finds NUKE and does not find Fallout.

### Outcome

Fallout is listed in the curated lists that still merge contributions. Lists that no longer merge anything are recorded here, so the same research is not repeated.

### Acceptance criteria

- [ ] An entry for Fallout is merged into at least one list with more than 1000 stars.
- [ ] Every list under consideration has a sub-issue recording its state and its submission link.
- [ ] Lists that are auto-generated or abandoned are named below with the reason to skip them.

### Skip these — researched 2026-07-30

Auto-generated, ignores pull requests:

- `uhub/awesome-c-sharp` — bot commits monthly as `uhub `. 15 pull requests since 2021, none merged.
- `Correia-jpv/fucking-awesome-dotnet-core`, `icopy-site/awesome`, `trackawesomelist/trackawesomelist` — mirrors that regenerate from an upstream list. They pick Fallout up automatically once an upstream list merges.

Abandoned. Date in brackets is the last merged pull request:

- `jasonhua95/awesome-dotnet-core` (2021-02)
- `mehdihadeli/awesome-dotnet-core-education` (2022-02)
- `aws/dotnet-foss` (2023-07)
- `dotnet-easy/easy-dotnet` (2023-10)
- `Mwaseemzakir/awesome-dotnet-resources` (2024-07)
- `ara3d/extra-awesome-dotnet` (never merged one)
- `jobbole/awesome-dotnet-cn` (repo untouched since 2022)
