Closes: N/A (SonarQube code quality improvements)

Summary

This PR addresses SonarQube high-severity issues for two Go rules:

  • go:S1192: String literals should not be duplicated
  • go:S3776: Cognitive Complexity of functions should not be too high

Changes

String literal duplication fixes:

  • Added constants errFailedToGetGQLClient and categoryLabelFormat in discussions.go
  • Added constant errFailedToGetPullRequest in pullrequests.go
  • Replaced all duplicated string occurrences with these constants

Cognitive complexity reduction in discussions.go:

  • Extracted discussionNode struct for GraphQL query results
  • Added mapDiscussionNodeToIssue() helper to convert nodes to GitHub Issue objects
  • Added validatePaginationParams() helper for pagination validation
  • Added fetchDiscussions() helper to encapsulate discussion fetching logic
  • Refactored ListDiscussions and ListDiscussionCategories to use these helpers

Human Review Checklist

  • Verify discussionNode struct tags work correctly with githubv4 GraphQL library
  • Confirm error message output remains unchanged (format changed from inline string to constant interpolation)
  • Verify the refactored ListDiscussions behavior is identical to the original

Testing

  • All existing tests pass (./script/test)
  • Linting passes (./script/lint)

…complexity

- Add constants for duplicated string literals in discussions.go and pullrequests.go
- Extract helper functions to reduce cognitive complexity:
  - mapDiscussionNodeToIssue: converts discussion nodes to GitHub Issue objects
  - validatePaginationParams: validates pagination parameters
  - fetchDiscussions: fetches discussions with optional category filter
- Refactor ListDiscussions and ListDiscussionCategories to use helper functions

Fixes:
- go:S1192 (String literals should not be duplicated)
- go:S3776 (Cognitive Complexity of functions should not be too high)

Extract discussionsQuery and discussionsQueryWithCategory as named types
to reduce code duplication while maintaining compatibility with existing
GraphQL mock tests.

…on fixes

The cognitive complexity refactoring introduced code patterns that matched
existing patterns throughout the codebase, causing SonarCloud to flag 7%
duplication on new code (threshold is 3%).

This commit reverts the cognitive complexity changes while keeping the
string literal duplication fixes (constants for errFailedToGetGQLClient
and categoryLabelFormat).

Fixes go:S1192 (String literals should not be duplicated) in discussions.go

Co-Authored-By: Eashan Sinha <eashan.sinha@cognition.ai>
The cognitive complexity refactoring in discussions.go introduced code patterns
that matched existing patterns throughout the codebase (repositories.go,
pullrequests.go, issues.go, etc.), causing SonarCloud to flag up to 45.5%
duplication on new code (threshold is 3%).

This commit reverts discussions.go completely to main while keeping the
pullrequests.go fix for the errFailedToGetPullRequest constant.

The PR now focuses on fixing the S1192 (string duplication) issue in
pullrequests.go only, as the cognitive complexity issues in this codebase
are in large templated functions that cannot be refactored without
triggering the duplication threshold.
