feat: asset library pipeline for entity icons

[madjin]

Summary

Pipeline for extracting entities from daily content and sourcing visual assets (icons/logos).

• extract-entities.py: Added --normalize-only flag for LLM deduplication without re-extraction
• fetch-icons.py: CoinGecko integration with rate limiting (3s/req) and pre-scan for efficiency
• generate-asset-checklist.py: Coverage reporting with fuzzy containment matching
• 200+ icons across tokens/plugins categories

Current Coverage

Category	Coverage
Tokens	20% (19/96)
Platforms	17% (33/189)
Tech	11% (18/157)
Projects	14% (34/244)
Plugins	30% (53/175)

Test plan

• python scripts/posters/fetch-icons.py --tokens - pre-scans existing, skips API calls
• python scripts/posters/generate-asset-checklist.py - generates coverage report
• python scripts/etl/extract-entities.py --normalize-only -i <inventory> - normalizes without re-extraction

Code review

Found 1 issue:

1. Schema mismatch causes immediate runtime failure - load_entities() expects the old dict-based schema {"entities": {"category": [items]}} but manifest.json now uses a flat list schema {"entities": [{"name": "...", "type": "..."}]}. This causes AttributeError: 'list' object has no attribute 'items' when the script runs.

knowledge/scripts/posters/generate-asset-checklist.py

Lines 71 to 80 in 7ef9af9

	result = {}
	for category, items in data.get("entities", {}).items():
	# Dedupe by lowercase, keep original for display
	seen = {}
	for item in items:
	key = item.lower()
	if key not in seen:
	seen[key] = item
	result[category] = seen
	return result

The code at line 72 calls .items() on data.get("entities", {}), but after the refactor from entity-inventory.json to manifest.json, entities is now a list, not a dict.
