feat(tips): add 69 deeper hidden-gem tips (279 total) (#8237)

Add lesser-known power-user tips covering:
- BOOT.md gateway startup automation
- Cron script attachment for data collection pipelines
- Prefill messages for few-shot priming
- Focus topic compression (/compress <topic>)
- Terminal exit code annotations and auto-retry
- Automatic sudo password piping
- execute_code built-in helpers (json_parse, shell_quote, retry)
- File loop detection and staleness warnings
- MCP sampling and dynamic tool discovery
- Delegation heartbeat and ACP child agents (Claude Code)
- 402 auto-fallback in auxiliary client
- Container mode, HERMES_HOME_MODE, subprocess HOME isolation
- Ctrl+C 5-tier priority system
- Browser CDP URL override and stealth mode
- Skills quarantine, audit log, and well-known protocol
- Per-platform display overrides, human delay mode
- And many more deep-cut features
