refactor(brand): rename F∆I -> Ch∆In + hub binary fai -> chain
Some checks failed
Security / Security check (push) Failing after 2s
Details

Browse source 
Studio follows the platform rename: product branding F∆I -> Ch∆In in UI
strings, command examples fai -> chain, and — critically — the spawned
hub binary path ~/.fai/bin/fai -> ~/.fai/bin/chain so Studio launches
the renamed binary. The fai_* Dart identifiers (FaiLog, widget files,
the generated SDK) stay = vendor/internal namespace. flutter analyze:
no issues.
