Adds docs/benchmarking.md walking the full TUI journey — download a model, serve it, run a live benchmark, and share results as an auto-opened PR — with four annotated screenshots in assets/. README banner and Documentation table now point to the guide. The TUI guide gains the previously undocumented "Benchmark this model" popup keys, and the leaderboard docs are reframed community-first: llmfit community submissions are the primary data source, localmaxxing.com is supplemental, with the trust order spelled out to match cli.md.
