[WIP] Fix lint Go issues

[Copilot]

Fix Go Linting Issues

• Fix staticcheck S1009 issues in compiler_safe_outputs_core.go (lines 962, 977) - remove redundant nil checks for slices
• Remove unused variable prSafeOutputsLog in compiler_safe_outputs_prs.go (line 7)
• Remove unused functions getCloseDiscussionScript and getCloseIssueScript in js.go (lines 30-31)
• Run linter to verify all issues are fixed
• Run tests to ensure changes don't break functionality

Changes Made

1. compiler_safe_outputs_core.go: Removed redundant != nil checks before len() calls on slices (lines 962, 977)

   • In Go, len() on a nil slice returns 0, so the nil check is unnecessary

2. compiler_safe_outputs_prs.go: Removed unused logger variable prSafeOutputsLog

   • This logger was declared but never used in the file

3. js.go: Removed unused functions getCloseDiscussionScript and getCloseIssueScript

   • These functions were placeholders that returned empty strings and were never called

All lint issues have been resolved and tests pass successfully.
