Update SDK to latest state

[martti007]

• Moved commons library functionality into SDK

[Copilot]

Pull Request Overview

This PR migrates functionality previously provided by the external commons library into the SDK, refactors token/transaction models and verification flows, and updates tests accordingly.

• Replaces commons APIs with internal CBOR, hashing, SMT/SMST, signing, and predicate implementations
• Refactors Token, Transactions (mint/transfer), Commitments, and verification pipeline; adjusts JSON/CBOR formats
• Updates unit/functional/e2e tests and utilities to the new SDK interfaces

toCBOR omits the coinId, but fromCBOR expects the tuple [coinId, aggregationPath, coinTreePath]. This breaks round‑trip serialization and downstream verification. Serialize coinId as the first element.

Suggested change

	return CborSerializer.encodeArray(this.aggregationPath.toCBOR(), this.coinTreePath.toCBOR());
	return CborSerializer.encodeArray(
	this.coinId.toCBOR(),
	this.aggregationPath.toCBOR(),
	this.coinTreePath.toCBOR()
	);

The error references data[4] instead of the actual version at data[0], producing a misleading message. Capture the version from data[0] and report it.

Suggested change

	throw new Error(`Unsupported token version: ${CborDeserializer.readTextString(data[4])}`);
	throw new Error(`Unsupported token version: ${CborDeserializer.readTextString(data[0])}`);

Use the generic parameter C for the rule type to preserve type safety and avoid needless widening to IVerificationContext. Replace VerificationRule with VerificationRule.

Suggested change

	let rule: VerificationRule<IVerificationContext> | null = this.firstRule;
	let rule: VerificationRule<C> | null = this.firstRule;

[Copilot]

The class docstring refers to 'Mint transaction' and a generic mint reason, but this class models a transfer transaction and has no type parameter. Update the comment to accurately describe a transfer transaction.

Suggested change

	* Mint transaction.
	*
	* @param <R> mint reason
	* Represents a transfer transaction, including its data and inclusion proof.

[Copilot]

toString labels the field as 'isSuccessful' but prints the numeric status code. Print this.isSuccessful (boolean) and, optionally, include status on a separate line.

Suggested change

	isSuccessful: ${this.status}
	isSuccessful: ${this.isSuccessful}
	status: ${this.status}

[Copilot]

The JSDoc does not match the method behavior. getReference returns a predicate reference, not raw CBOR bytes. Update the summary and @return to reflect that it returns UnmaskedPredicateReference.

Suggested change

	* Convert predicate to CBOR bytes.
	*
	* @return CBOR bytes
	* Returns a reference to this predicate for use in transactions.
	*
	* @return Promise resolving to an UnmaskedPredicateReference

[Copilot]

Corrected spelling.

Suggested change

	// Perfrom 1st split
	// Perform 1st split

could be a link to an enum, unclear which values are acceptable
