discover-channels: extractHandle('youtube') now detects UC* channel IDs
and returns them without @ prefix (previously @UC... caused verify fail)
verifyHandles: verifyYouTube uses cleanHandle for UC* check, requests
part=id,snippet for richer data
collect-channel-data: if channelId missing but handle present, resolves
via forHandle/forUsername lookup or direct UC* detection before skipping

discover-channels: new extractHandle() validates each handle belongs to
its platform (rejects hospital-internal URLs like /idtube/view being
treated as YouTube). Extracts handles from full URLs correctly.
collect-channel-data: explicit Record<string,unknown> typing for DB JSON
fields — fixes TypeScript property access on VerifiedChannels from DB.
verifyHandles: fix TikTok double-URL concatenation.

Restructured the entire analysis pipeline from AI-guessing social
handles to deterministic 3-phase discovery + collection + generation.
Phase 1 (discover-channels): 3-source channel discovery
- Firecrawl scrape: extract social links from HTML
- Perplexity search: find handles via web search
- URL regex parsing: deterministic link extraction
- Handle verification: HEAD requests + YouTube API
- DB: creates row with verified_channels + scrape_data
Phase 2 (collect-channel-data): 9 parallel data collectors
- Instagram (Apify), YouTube (Data API v3), Facebook (Apify)
- 강남언니 (Firecrawl), Naver Blog + Place (Naver API)
- Google Maps (Apify), Market analysis (Perplexity 4x parallel)
- DB: stores ALL raw data in channel_data column
Phase 3 (generate-report): AI report from real data
- Reads channel_data + analysis_data from DB
- Builds channel summary with real metrics
- AI generates report using only verified data
- V1 backwards compatibility preserved (url-based flow)
Supporting changes:
- DB migration: status, verified_channels, channel_data columns
- _shared/extractSocialLinks.ts: regex-based social link parser
- _shared/verifyHandles.ts: multi-platform handle verifier
- AnalysisLoadingPage: real 3-phase progress + channel panel
- useReport: channel_data column support + V2 enrichment merge
- 강남언니 rating: auto-correct 5→10 scale + search fallback
- KPIDashboard: navigate() instead of <a href>
- Loading text: 20-30초 → 1-2분

- enrich-channels: Instagram fallback — auto-try _ps, .ps, _clinic suffixes when <100 followers
- enrich-channels: YouTube URL normalization via normalizeYouTubeChannel (handles /c/, /user/, @handle)
- enrich-channels: Google Maps multi-query search for better hit rate
- generate-report: AI-found social handles prioritized over Firecrawl scrape
- generate-report: Added socialMedia field to AI prompt for accurate handle discovery
- normalizeHandles: Added normalizeYouTubeChannel for /c/, /user/, /channel/, @handle URLs

- Add normalizeInstagramHandle() utility (Edge + browser) to strip URLs, @ prefixes
- generate-report: normalize handles before saving, persist socialHandles in report JSONB
- enrich-channels: normalize Instagram handle before Apify call (defense in depth)
- useReport: recover socialHandles + channelEnrichment from DB on direct URL access
- ReportPage: skip redundant enrichment when data already exists in DB
Fixes: Instagram enrichment failing due to URL-format handles passed to Apify
