Summary

Update google/go-github from v82 to v86, fixing all breaking API changes across the four major versions.

Why

Fixes #
Keeping dependencies up to date for bug fixes, security patches, and new API support. v83–v86 include security improvements (cross-host redirect
rejection, URL path traversal protection, webhook payload size limits) and new GitHub API coverage.

• pkg/github/issues.go: Replace removed IssueListOptions with ListOptions for SubIssue.ListByIssue (v84)
• pkg/github/notifications.go: MarkThreadDone now takes string instead of int64 (v85) — removed unnecessary strconv.ParseInt conversion and unused
  strconv import
