e2b1a9f8ac feat: add Review Comment Generator (Issue #126)
Some checks failed
Test / pytest (pull_request) Failing after 7s
- Introduces scripts/review_comment_generator.py: reads JSONL findings,
  deduplicates by content hash, formats as review comments, and posts
  to Gitea PR via API.
- Includes dry-run and JSON output modes.
- Comprehensive smoke test suite: 20 tests covering deduplication,
  formatting, CLI modes, and error handling — all passing.

Closes #126

"""
knowledge_synthesizer.py — Zero-shot knowledge synthesis for compounding intelligence.
Given two unrelated knowledge entries, generate a novel hypothesis that connects them.
Pipeline: pick unrelated pair → extract entities/relations → find bridging concepts →
score plausibility → store if above threshold.
Usage:
python3 scripts/knowledge_synthesizer.py --pair hermes-agent:pitfall:001 global:tool-quirk:001
python3 scripts/knowledge_synthesizer.py --auto --threshold 0.75
python3 scripts/knowledge_synthesizer.py --dry-run # show candidate pair without synthesizing

# Knowledge Synthesis Prompt
## System Prompt
You are a knowledge synthesis engine. Given two facts, you generate a novel hypothesis
that connects them in a way no human would typically link — a zero-shot creative leap.
## Task
FACT A:
{fact_a}
FACT B:
{fact_b}
Generate a single JSON object:
{
"hypothesis": "one concise sentence linking the two facts as a new, testable insight",
"plausibility": 0.0-1.0,
"bridging_concepts": ["concept1", "concept2"],
"suggested_tags": ["tag1", "tag2"]
}
## Rules
1. The hypothesis must be a logical consequence of combining both facts.
2. DO NOT restate either fact — produce genuinely new insight.
3. Plausibility should reflect confidence given only these two facts.
4. If no meaningful connection exists, return {"hypothesis":"","plausibility":0.0}.
5. Output ONLY valid JSON — no markdown, no explanation.
## Examples
Input facts:
- "Gitea PR creation requires branch protection approval (1+) on main"
- "Git push hangs on large repos (pack.windowMemory=100m)"
Hypothesis output:
{
"hypothesis": "Branch protection triggers checks that inflate pack size, causing git push to hang on large repos",
"plausibility": 0.65,
"bridging_concepts": ["git", "gitea", "branch-protection", "push"],
"suggested_tags": ["git", "gitea", "performance"]
}
Output ONLY the JSON object.
