replace Oishii example with time orchestrator built by agent teams

Agent teams now bootstrap a self-contained time orchestration workflow
inside agent-teams/.claude/ (command, agent, skill). The prompt, diagram,
and How to Use section all reference the new time-orchestrator pattern
with cd agent-teams && claude → /time-orchestrator.

+# Time SVG Creator Skill
+
+Creates a visual SVG time card for Dubai, UAE and writes the output files.
+
+## Task
+
+You will receive three fields from the calling context: `time`, `timezone`, and `formatted`. Create an SVG time card and write both the SVG and a markdown summary.
+
+## Instructions
+
+1. **Create SVG** — Use the SVG template from [reference.md](reference.md), replacing placeholders with actual values
+2. **Write SVG file** — Write to `agent-teams/output/dubai-time.svg`
+3. **Write summary** — Write to `agent-teams/output/output.md` using the markdown template from [reference.md](reference.md)
+
+## Rules
+
+- Use the EXACT time values provided — NEVER re-fetch or recalculate
+- The SVG must be self-contained and valid
+- Both output files go in the `agent-teams/output/` directory
+
+## Additional resources
+
+- For SVG template, output template, and design specs, see [reference.md](reference.md)
+- For example input/output pairs, see [examples.md](examples.md)
