fix: update for Gradio 5+/6+ compatibility

- Move theme from gr.Blocks() to app.launch() (Gradio 6 API change)
- Update requirements to gradio>=5.0.0 for websockets 13+ support
- websockets 13+ required by supabase realtime module

Tested locally with fresh venv install.

+# Johnny Harris Knowledge Base
+
+Vector database of Johnny Harris YouTube transcripts for style replication and topic search.
+
+## Database: `johnny_transcripts`
+
+| Column | Type | Description |
+|--------|------|-------------|
+| `video_id` | text | YouTube video ID |
+| `video_url` | text | Full YouTube URL |
+| `title` | text | Video title |
+| `chunk_text` | text | ~1000 words of transcript |
+| `chunk_index` | int | Position in video (0, 1, 2...) |
+| `total_chunks` | int | Total chunks for this video |
+| `embedding` | vector(1024) | Jina v3 embedding |
+
+## Querying
+
+### 1. Similarity Search (Tab 1: Topic Coverage)
+
+Embed the user's query with Jina v3, then find similar chunks:
+
+```python
+from supabase import create_client
+
+# Embed query with Jina v3
+query_embedding = jina_embed(user_query)  # returns 1024-dim vector
+
+# Find similar chunks
+result = supabase.rpc('match_transcripts', {
+    'query_embedding': query_embedding,
+    'match_threshold': 0.7,
+    'match_count': 10
+}).execute()
+
+# Returns: title, video_url, chunk_text, similarity score
+```
+
+### 2. Title Search (Quick lookup)
+
+For simple keyword matching on titles:
+
+```python
+result = supabase.from_('johnny_transcripts') \
+    .select('title, video_url') \
+    .ilike('title', f'%{keyword}%') \
+    .execute()
+```
+
+### 3. Get Full Context (Tab 2: Script Production)
+
+After finding relevant chunks, fetch surrounding context:
+
+```python
+# Get all chunks from a video for full context
+result = supabase.from_('johnny_transcripts') \
+    .select('chunk_text, chunk_index') \
+    .eq('video_id', video_id) \
+    .order('chunk_index') \
+    .execute()
+
+full_transcript = ' '.join([r['chunk_text'] for r in result.data])
+```
+
+## Gradio App Structure
+
+**Tab 1: Topic Search**
+- Input: Topic/question text
+- Process: Embed with Jina v3 → similarity search
+- Output: List of matching videos with titles, URLs, and relevant excerpts
+
+**Tab 2: Script Production**
+- Input: Bullet points, reference text, optional video links
+- Process:
+  1. Embed inputs → find similar Johnny content
+  2. Pass Johnny excerpts + user input to LLM
+  3. Generate script in Johnny's style
+- Output: Script draft with source citations
