Pull Request: Welcome DePIN Slayer

Greetings, Code Sorcerer!
Prepare to dazzle us with your wizardry in our modules. Whether you're tinkering with cams, tapping into something cool, or relaying important messages, we can't wait to see the magic.

What Spell Did You Cast?

Briefly explain the enchanted changes you've made:

• cam-module updates (for when you need to capture the moment)
• compute-node enhancements (AI vision meets blockchain verification)
• tap-module tweaks (tap, tap, tap – innovation at your fingertips)
• relay-node fixes (messages delivered, no carrier pigeons needed)

The Magic Unleashed:

Enhanced the compute-node with cryptographic firmware verification:

• Added firmware hash and signature verification from ESP32-CAM HTTP headers
• Implemented blockchain integration via PerformanceOracle smart contract
• Created ECDSA signature verification for tamper-evident metrics
• Updated documentation with geeky, fun explanations of the verification workflow

Show Off Your Magic:

The compute-node now securely fetches firmware verification from each camera:

[Device 1] Fetched FirmwareHash=0xa4d6e2c8f..., Signature=0x8e72b4d9a...
[Device 1] updateMetricsWithSig TX: 0x1f94db65bc73e8c86c9e8f7b0d3f6a2c...

Each detected face count is now cryptographically verified on-chain, ensuring metrics can't be faked!

Checklist:

• My code is modular and mighty.
• I've banished all bugs with rigorous testing.
• Documentation has been sprinkled with fairy dust (updated accordingly).
