Configure Architecture Guardian thresholds via repository-level .architecture.yml

[Copilot]

Architecture Guardian flagged multiple large-file and oversized-function violations using default thresholds because the repository had no .architecture.yml. This PR adds explicit architecture thresholds so scans use repo-defined limits instead of implicit defaults.

• What changed

  • Added a new root config file: .architecture.yml
  • Defined explicit threshold values for:
    • file blocker size
    • file warning size
    • function size warning
    • public export count info
  • Added inline comments to make severity semantics self-describing in-file.

• Why this addresses the issue

  • The architecture workflow already supports .architecture.yml; this enables configuration-based governance directly at repo root.
  • Future architecture reports now evaluate against declared policy, not fallback defaults.

thresholds:
  # Go/JS/CJS/MJS files above this line count are BLOCKER violations.
  file_lines_blocker: 2000
  # Go/JS/CJS/MJS files above this line count are WARNING violations.
  file_lines_warning: 1000
  # Go/JS/CJS/MJS functions above this line count are WARNING violations.
  function_lines: 200
  # Go/JS/CJS/MJS modules above this public export count are INFO violations.
  max_exports: 10
