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.

Different from the core `read`/`glob`/`grep` which work locally.\n\n**File tools** (remote host file operations):\n- **file_list** — list files and directories at a path on a target host.\n- **file_read** — read a file's contents on a target host.\n- **file_status** — get status of tracked files (modified, staged, untracked) on a target host.\n\n**Find tools** (remote search):\n- **find_files** — find files and directories by name (fuzzy match) on a target host.\n- **find_symbols** — find workspace symbols (functions, classes, variables) by name. Uses LSP.\n- **find_text** — search for text patterns (regex) in project files on a target host.\n\n**Workspace tools:**\n- **workspace_path** — get the server's current path and project context.\n- **workspace_vcs** — get git/VCS info: branch, dirty files, remotes.\n\nAll require a `host` parameter (fuji, sin, junkpile). Use these when you need to inspect files or search code on a remote host without SSH. The local equivalents (`read`, `glob`, `grep`) are faster for local work."
