docs(flashtestations-sdk): prepare SDK for initial public release with comprehensive documentation

This commit prepares the flashtestations-sdk for its initial public release by:

1. Overhauling documentation and cleaning up the public API surface.
2. Transforming the README from a generic TSDX template into comprehensive SDK documentation including
installation instructions, API reference, error handling guide, advanced usage patterns, and practical examples.
3. Unused example files (getBlock.ts and getTransactionReceipt.ts) have been removed

In a future commit we will update the version number to 1.0.0 and publish the SDK to npm

improving VerificationResult handling

- * Example: Check if a transaction is a flashtestation transaction
+ * Example: Check if a block contains a flashtestation transaction
  *
  * This example demonstrates how to:
- * 1. Create an RPC client for Unichain Sepolia (chain ID 1301)
- * 2. Check if a transaction emitted the BlockBuilderProofVerified event
- * 3. Retrieve the full transaction data if it's a flashtestation transaction
- * 4. Handle the case where the transaction is not a flashtestation
+ * 1. Use the getFlashtestationTx function to fetch flashtestation data from a block
+ * 2. Retrieve the full flashtestation event data if present
+ * 3. Handle the case where the block does not contain a flashtestation transaction
