refactor(skills): apply progressive disclosure to gitea skill

Split gitea skill into main file and reference documentation.
Main SKILL.md now focuses on core commands (154 lines, down from 201),
with setup/auth and CI/Actions moved to reference files.

+# Gitea Actions / CI
+
+Commands for debugging CI/Actions workflow failures in Gitea.
+
+## Workflow Runs
+
+```bash
+# List workflow runs
+tea actions runs                     # List all workflow runs
+tea actions runs -o json             # JSON output for parsing
+```
+
+## Jobs
+
+```bash
+# List jobs for a run
+tea actions jobs <run-id>            # Show jobs for a specific run
+tea actions jobs <run-id> -o json    # JSON output
+```
+
+## Logs
+
+```bash
+# Get job logs
+tea actions logs <job-id>            # Display logs for a job
+```
+
+## Full Workflow: Find Failed Job Logs
+
+```bash
+# 1. Find the run ID
+tea actions runs
+
+# 2. Find the job ID from that run
+tea actions jobs <run-id>
+
+# 3. View the logs
+tea actions logs <job-id>
+```
+
+## Tips
+
+- Use `-o json` with runs/jobs for programmatic parsing
+- Run IDs and Job IDs are shown in the output of the respective commands
+- Logs are displayed directly to stdout (can pipe to `grep` or save to file)
