refactor(communities): Enforce V2 architecture, remove V1 compatibility

**CONTEXT**: Pre-production system should not support V1 communities.
All communities must use V2 architecture from day one.

**CHANGES**:

1. **Jetstream Consumer** - Strict V2 validation:
- REJECT any community profile with rkey != "self"
- V1 used TID-based rkeys (e.g., "3km4..."), V2 uses "self"
- Removed V1 owner field handling
- Added clear error messages for V1 detection

2. **Lexicon Schema** - Removed V1 fields:
- Removed "owner" field (V1: owner != community DID)
- V2 principle: community IS the owner (self-owned)

3. **Domain Model** - Simplified ownership:
- Removed OwnerDID field from Community struct
- V2: owner_did always equals did (enforced at creation)

**V2 ARCHITECTURE PRINCIPLES**:
- Community owns its own PDS account (did)
- Community owns its own repository (at://did/...)
- Profile always at rkey="self" (not TID-based)
- Self-owned: owner_did == did (no separate owner)

**IMPACT**:
- Cleaner codebase without V1/V2 branching logic
- Prevents accidental V1 community creation
- Enforces architectural constraints at every layer
