chore: bump all compiler versions to 0.4.0, add Go/Zig/Ruby to bump script

Update schema and compiler version strings across all six compilers:
  TS:     runar-v0.4.0 / 0.4.0
  Go:     runar-v0.4.0 / 0.4.0-go
  Rust:   (uses crate version from Cargo.toml)
  Python: runar-v0.4.0 / 0.4.0-python
  Zig:    runar-v0.4.0 / 0.4.0-zig
  Ruby:   runar-v0.4.0 / 0.4.0-ruby

Also bump Zig package (build.zig.zon) and Ruby gem (runar.gemspec)
to 0.4.0.

The bump-version.sh script now handles:
  - Zig build.zig.zon package version
  - Ruby gemspec version
  - All compiler schema/version strings (TS, Go, Zig, Ruby, Python)
