test(issues): add 10 real function tests

Added tests for actual function calls that return values:
- countOpenIssues returns u16 in valid range
- buildStepComment returns allocated string with content
- buildStepComment handles all status types
- buildStepComment contains all required sections
- buildStepComment step/total formatting
- buildStepComment agent name appears correctly
- buildStepComment escapes special characters
- IssueTracker init sets owner and repo from git remote
- getIssuesByLabel allocates result array

Also fixed pre-existing test bugs:
- StepStatus has no label/emoji methods
- IssueStatus has no labels field (uses label_count)
- std.testing.testing typo

Total: 100 tests (was 90)
