- Add try/catch in claimUsername to handle UNIQUE constraint
- Return meaningful error: 'This public key has already claimed a different username'
- Enable observability logs for better debugging
## Breaking Changes
### Removed Endpoints
- Removed GET /users/:username/services (service listing)
- Services are now completely hidden - cannot be enumerated
### Updated Endpoints
- GET /users/:username/services/:fqn now supports semver matching
- Requesting chat@1.0.0 will match chat@1.2.3, chat@1.5.0, etc.
- Will NOT match chat@2.0.0 (different major version)
## New Features
### Semantic Versioning Support
- Compatible version matching following semver rules (^1.0.0)
- Major version must match exactly
- For major version 0, minor must also match (0.x.y is unstable)
- Available version must be >= requested version
- Prerelease versions require exact match
### Privacy Improvements
- All services are now hidden by default
- No way to enumerate or list services for a username
- Must know exact service name to discover
## Implementation
### Server (src/)
- crypto.ts: Added parseVersion(), isVersionCompatible(), parseServiceFqn()
- storage/types.ts: Added findServicesByName() interface method
- storage/sqlite.ts: Implemented findServicesByName() with LIKE query
- storage/d1.ts: Implemented findServicesByName() with LIKE query
- app.ts: Updated GET /:username/services/:fqn with semver matching
### Semver Matching Logic
- Parse requested version: chat@1.0.0 → {name: "chat", version: "1.0.0"}
- Find all services with matching name: chat@*
- Filter to compatible versions using semver rules
- Return first match (most recently created)
## Examples
Request: chat@1.0.0
Matches: chat@1.0.0, chat@1.2.3, chat@1.9.5
Does NOT match: chat@0.9.0, chat@2.0.0, chat@1.0.0-beta

## Breaking Changes
### Server
- Services can now have multiple offers instead of single offer
- POST /users/:username/services accepts `offers` array instead of `sdp`
- GET /users/:username/services/:fqn returns `offers` array in response
- GET /services/:uuid returns `offers` array in response
- Database schema: removed `offer_id` from services table, added `service_id` to offers table
- Added `batchCreateServices()` and `getOffersForService()` methods
### Client
- `PublishServiceOptions` interface: `offers` array instead of `sdp` string
- `Service` interface: `offers` array instead of `offerId` and `sdp`
- `ServiceRequest` interface: `offers` array instead of `sdp`
- RondevuSignaler.setOffer() sends offers array to server
- Updated to extract offerId from first offer in service response
## New Features
- Support for multiple simultaneous offers per service (connection pooling)
- Batch service creation endpoint for reduced server load
- Proper one-to-many relationship between services and offers
## Implementation Details
### Server Changes (src/storage/)
- sqlite.ts: Added service_id column to offers, removed offer_id from services
- d1.ts: Updated to match new interface
- types.ts: Updated interfaces for Service, Offer, CreateServiceRequest
- app.ts: Updated all service endpoints to handle offers array
### Client Changes (src/)
- api.ts: Added OfferRequest and ServiceOffer interfaces
- rondevu-service.ts: Updated PublishServiceOptions to use offers array
- rondevu-signaler.ts: Updated to send/receive offers array
## Migration Notes
- No backwards compatibility - this is a breaking change
- Services published with old API will not work with new server
- Clients must update to new API to work with updated server
🤖 Generated with Claude Code
- Delete unused bloom.ts module (leftover from topic-based discovery)
- Remove maxTopicsPerOffer configuration (no longer used)
- Remove unused info field from Offer types
- Simplify generateOfferHash() to only hash SDP (remove topics param)
- Update outdated comments referencing deprecated features
- Remove backward compatibility topics field from answer responses
This completes the migration to V2 service-based architecture by
removing all remnants of the V1 topic-based system.

- d1.ts: Use global crypto.randomUUID() instead of importing from 'crypto'
- sqlite.ts: Use 'node:crypto' import for Node.js compatibility
This fixes the Cloudflare Workers deployment error:
"The package 'crypto' wasn't found on the file system but is built into node"

- Removed PUT /offers/:offerId/heartbeat endpoint
- Removed updateOfferLastSeen() from storage interface and implementations
- last_seen column is still in DB but not used for cleanup
- Cleanup only uses expires_at, so heartbeat was non-functional
