refactor(simphtml): rewrite list detection & cutlist for multi-list support

- simphtml: replace center-point ancestor-chain approach with global container scan;
  support multiple lists per page; add container-scoped selector prefixes;
  inline FAKE ELEMENT hints with hidden item previews; remove findMainContent
- ga: hot-reload simphtml on each web_scan; fix file_read total_lines for keyword search;
  add errors='replace' for global_mem encoding safety
- llmcore: stabilize NativeClaude session/device IDs across requests;
  rename no_system_prompt to fake_cc_system_prompt; deep-copy message content
- launch: adjust window width 700->600
