High level description

Improve IPFS peering at startup

Detailed description

• Remove IPFS Cluster from testnet
• Deterministic full-mesh peering at startup: node publishes PeerID, configures Peering.Peers from peer metadata
• Improve cloudagent IPFS client behaviour by adding explicit timeouts for cat/add requests

Describe alternatives you've considered

Operational impact

Additional context

Biggest changes are to the IPFS unit test suite to match the format of the other cloudagent unit tests. All tests still present, now extended for new timeout logic.

Pull request overview

This PR improves IPFS network stability by removing the IPFS Cluster dependency and implementing deterministic peer discovery with explicit timeouts for IPFS operations.

Changes:

• Added 15-second timeout handling to IPFS client methods (getFile and uploadFile) using AbortController
• Replaced IPFS Cluster with deterministic full-mesh static peering via shared peer metadata volume
• Updated IPFS startup script to configure DHT routing, static peering, and wait for all nodes before starting
• Removed all IPFS Cluster containers and volumes from docker-compose-testnet.yml
• Modified IPFS health checks to verify daemon readiness and peer connectivity

File	Description
src/ipfs/index.ts	Added AbortController-based timeout handling (15s) for getFile and uploadFile operations with improved error messages
docker/ipfs/ipfs-startup.sh	Implemented deterministic peer discovery using shared volume for peer IDs, configured full-mesh static peering, and enabled accelerated DHT
docker/ipfs/Dockerfile	Created /ipfs-peerdata directory with proper permissions for peer metadata sharing
docker-compose-testnet.yml	Removed IPFS Cluster containers (cluster0, cluster1, cluster2), added ipfs-peerdata volume, updated health checks, and added IPFS_NODE_NAME environment variables
