fix(tools): upgrade golangci-lint to v2.5.0 and add new tools to upgrade workflow

Fixed two critical issues with tool upgrade system:

1. golangci-lint upgrade not working (v1.64.8 → v2.5.0)
   - Root cause: go install @latest only knew about v1.64.8 from Go module proxy
   - GitHub releases had v2.5.0, but not published to Go module ecosystem yet
   - Fix: Prioritize GitHub binary download over go install for authoritative version
   - Changed install_golangci_lint() to try GitHub releases first, go install as fallback
   - Result: Successfully upgrades from v1.64.8 to v2.5.0

2. New tools not offered in make upgrade (git-lfs, tfsec, ninja, cscope)
   - Root cause: CORE_TOOLS array in scripts/guide.sh was missing new tools
   - Tools were added to cli_audit.py but not to upgrade workflow
   - Fix: Added git-lfs, semgrep, pre-commit, tfsec, ninja, cscope to CORE_TOOLS array
   - Result: All 68 tracked tools now appear in interactive upgrade prompts

Changes:
- scripts/install_core.sh: Reordered golangci-lint installation (GitHub first)
- scripts/guide.sh: Added 6 new tools to CORE_TOOLS array
- Maintained existing functionality for all other tools
