docs: fix ambient.json field documentation to match platform reality

Audited all ambient.json fields against the platform runner code
(ambient-runner) and corrected documentation that didn't match:

- startupPrompt: Document that it's sent TO the agent as a hidden user
  message, not displayed to the user. Update all examples to use
  directive style instead of canned greetings.
- greeting: Remove — field is not implemented in the platform.
- enabled: Remove — not read from ambient.json by the runner.
- rubric: Remove — only partially implemented, doesn't fit long-term
  strategy of keeping ambient.json lightweight and portable.
- results: Clarify it's informational only, not read by the platform
  at runtime.
- Remove fictional optional fields (version, author, tags, icon) from
  FIELD_REFERENCE docs and workflow-creator skill.
- Fix stale code paths (claude-code-runner → ambient-runner).

 ### startupPrompt
 - **Type:** string
-- **Purpose:** Initial message when workflow activates
+- **Purpose:** Sent to the agent as a hidden user message at session start; the user never sees it, only the agent's response
 - **Current Value:** See `.ambient/ambient.json`
 - **Guidelines:**
-  - Greet user warmly
-  - List available commands
-  - Provide clear next steps
+  - Write as a directive to the agent (e.g., "Greet the user and introduce yourself as...")
+  - Tell the agent to list available commands and ask what the user needs
