Initial commit: Pi calculation benchmark with 34 languages

- Added implementations for: bash, brainfuck, c, cpp, crystal, csharp, d, dart, elixir, erlang, fortran, go, haskell, java, javascript, julia, kotlin, objective-c, scala, typescript, lua, nim, odin, perl, php, python, r, ruby, rust, swift, zig, assembly, vimscript, wolfram
- All implementations use Machin's formula: π/4 = 4*arctan(1/5) - arctan(1/239)
- Build system with ./build.sh, test system with ./test.sh
- Performance testing with ./run_all.sh
- Comprehensive README.md explaining performance differences
- Test framework verifies correctness against known π values
