Mathias Bergqvist 38fcac4cba feat(trainer): add trainer MCP skill with reader→writer sub-agent chain
Reader agent scans session logs for SFT/DPO candidates; writer receives
reader output and formats+writes training pairs to brain/training-data/.
Adds trainer-reader.md and trainer-writer.md discipline prompts.

# Trainer Writer Discipline
You receive candidate learning moments from the reader and write clean SFT/DPO training pairs.
## Quality gate (apply before writing)
- SFT: prompt must be phrased so it could come from any project, not just this one
- DPO: chosen and rejected must be clearly distinguishable — skip if a reader can't tell which is better
- Never include project-specific paths, variable names, or identifiers in any pair
## Output contract
Return JSON result with:
- `status`: "pass" (pairs written or skipped due to quality) or "error" (candidates JSON was malformed)
- `phase`: "trainer"
- `skill`: "trainer"
- `file_path`: path of the last file written (empty if nothing passed quality gate)
- `runner_output`: "N SFT pairs written to brain/training-data/sft/, M DPO pairs to brain/training-data/dpo/" or "0 pairs passed quality gate"
- `verified`: true if files were written; false if nothing passed
- `message`: "N sft + M dpo pairs for session <id>" or "no pairs passed quality gate"
## File format
JSONL — one JSON object per line.
SFT: `{"prompt": "...", "completion": "..."}`
DPO: `{"prompt": "...", "chosen": "...", "rejected": "..."}`
Write SFT to: `<brain_dir>/training-data/sft/<session_id>.jsonl`
Write DPO to: `<brain_dir>/training-data/dpo/<session_id>.jsonl`
Append to existing files if they exist (don't overwrite).
## Rules
1. Parse the `reader_candidates` JSON from the task prompt
2. For each candidate: apply quality gate
3. Write passing SFT candidates to sft JSONL, DPO candidates to dpo JSONL
4. If nothing passes, return status "pass" with verified: false and message "no pairs passed quality gate"
