feat: migrate bindings to curried API

[dbrattli]

Summary

• migrate every public OTP and JSX binding module to one curried, pipe-friendly F# surface
• replace public ImportAll objects in Timer, Io, GenServer, Supervisor, Ets, Logger, and Jsx; retain only internal implementation bindings where appropriate
• use local module aliases in tests (BString, BGenServer, BEts, etc.) so binding operations stay scoped
• update README examples and complete the public-module conversion checklist in API-SURFACES.md

Validation

• dotnet build test/ -m:1
• Fable to Erlang, rebar3 compilation, and BEAM test run: 412 passed
• just format-check

just test still encounters its known parallel dotnet build test failure with no diagnostics; the equivalent serial pipeline above passed.
