chore(all|pr_compliance): remove duplicate pre-commit; update needs

[What]
Remove duplicated pre-commit invocation from main workflow and make platform jobs depend directly on PR Compliance via needs.

[Why]
Avoid running pre-commit twice on PRs and ensure all jobs are strictly gated by PR Compliance.

[How]
- .github/workflows/main.yml: drop pre-commit job; set ubuntu/mac/windows to needs: [pr_compliance].

Scope:
- Task: 0
- Variant: 0
- Technology: all
- Folder: pr_compliance

Tests:
- CI: workflow graph shows no duplicate pre-commit; downstream jobs start only after pr_compliance.

Local runs:
- N/A (workflow change only)
