fix(observer): v12 — skip prompt-only code text + enrichment validation (v0.5.44) #task-619

- extractContextFromNearby: PROMPT_ONLY_RE skips code elements containing only terminal prompts (e.g. '\\gravity_control >')
- Multi-codeEl traversal: tries all code elements at each depth, picks longest non-prompt text
- http-bridge enrichment: validates extracted command is not just a prompt fragment before enriching
- Fixes: cmd='\\gravity_control >' (prompt-only) no longer sent to Discord as the command text
