feat(skills): add jira-workflow, repo-map, docs-map, go-standards

- descriptions state WHEN each skill applies
- jira-workflow ships curl scripts reading TRACKER_URL/JIRA_TOKEN from env, no hardcoded secrets/URLs
- repo-map/docs-map defer values to session corporate context; company specifics left as TODO
- go-standards uses realistic Go defaults, company-specific bits marked TODO
