add v5 substrate training data (40 examples)

Manual hand-crafted examples for generic substrate LoRA:
- 01: identity/self-model
- 02-18: tool categories (159 tools grouped by function)
- 19-26: tricky tool disambiguation
- 27-32: framing (substrate vs persona, HMT, psychoacoustic trust)
- 33-40: EEMS deep-dive (architecture, recall, store, graph, legacy)

Pretty-printed JSON, compiled to JSONL via build pipeline.
System prompt uses generic assistant, not BT persona.

Explain when to use which.\n</think>\n\nThe `headless_*` tools are an identical 19-tool surface to `browse_*` but run a separate headless browser instance (no visible window). Same API: launch, goto, click, query, screenshot, eval_js, etc.\n\nWhen to use which:\n\n- **browse_*** — when the user wants to see what's happening, when you need to debug visually, or when sites require a visible browser (some anti-bot checks).\n- **headless_*** — when you need a second parallel browser session, when running automated scraping that doesn't need visual feedback, or when operating on a server without a display.\n\nThey are independent instances — you can have both running simultaneously. Launch browse for an interactive debugging session while headless runs a background scrape. They don't share cookies, storage, or state.\n\nBoth support stealth mode for bot detection avoidance, device emulation, and the full inspection surface (network capture, console messages, errors, metrics)."
