chore: Refactor Gobo script; add config

[EttyKitty]

Summary by cubic

Add .goborc.json with formatting rules and refactor the formatter script to be cross‑platform, auto‑download the correct gobo binary, run once over the project, and show a clear results summary. Remove the legacy run_gobo.bat.

• Refactors
  • Added .goborc.json (4-space indent; vertical arrays/structs; no multiline ternary; explicitUndefined: false).
  • Reworked run_gobo.ps1: detects Windows/Linux/macOS, downloads/extracts the right asset (.zip/.tar.gz), sets exec perms, runs gobo once, captures stdout/stderr, parses [Warn]/[Error], reports files processed and time, and sets exit codes.
  • Removed run_gobo.bat.

^{Written for commit a4ca8c8. Summary will update on new commits.}

Shadow auto-approve: would auto-approve. All changes are either formatting (blank lines, commas, spacing) enforced by the new gobo config, or the addition of explicit undefined for omitted optional arguments, which is semantically equivalent and safe.
