Adds two improvements to the user/org/repo project-board REST API: * state filter on column-issues endpoints (issue #4) GET /api/v1/{users,orgs}/{name}/-/projects/{id}/columns/{col}/issues GET /api/v1/repos/{owner}/{repo}/projects/{id}/columns/{col}/issues Now accept ?state=open|closed|all (default open), matching the convention on the project-list endpoint and on /repos/.../issues. Applied at the IssuesOptions layer so all three scopes inherit the filter. * populated num_issues / num_open_issues / num_closed_issues on column-list (issue #5) ColumnList.LoadIssueCounts runs two grouped queries against project_issue joined with issue (one open, one closed). All three List*Columns handlers call it before converting, so num_issues stops being null and consumers can render a kanban summary in a single round trip instead of N+1. Tests: * unit: empty-input fast path on ColumnList.LoadIssueCounts. * integration: extended testAPIListProjectColumnIssues / -User / -Org to close an issue, then verify default=open hides it, state=closed and state=all return it, and the column-list response carries the correct open/closed/total split. Closes #4, closes #5
