refactor(config): parse Glendix TOML with tom

[GG-O-BP]

Summary

• replace the handwritten JavaScript TOML reader with a typed Gleam configuration boundary built on simplifile and tom
• parse [tools.glendix] once per command operation and pass typed bindings across the JavaScript effect boundary
• preserve missing-file/table defaults while returning descriptive errors for malformed TOML and invalid configured value types
• document strict TOML behavior in the English, Korean, and Japanese READMEs
• add focused configuration tests for defaults, package-manager/compatibility settings, bindings, quoted keys/comments, malformed input, and invalid types

Validation

• mandatory pre-push ./scripts/verify.sh final
  • format/check/warnings/docs/style/FFI/repository-boundary gates
  • standalone consumers and all package tests
  • Glendam browser integration
  • widget MPK build
  • Lustre browser E2E
  • Mendix 11.12 full build/runtime/browser E2E
• dependency commit policy: passed
• git diff --check: passed

The host's WinBoat container normally owns port 8080, so it was stopped by container name during Mendix verification and restored afterward. Hex API rate-limit failures were handled by retrying only the dependency-download operation after the rate-limit window reset.

Closes #15
