 *
 * This function:
 * 1. Initializes a new change (proposal) in the CDN.
 * 2. Executes the provided `executeChanges` function to upload assets or WASM.
 * 3. If changes were uploaded, submits the proposal.
 * 4. Logs metadata (ID, status, hash).
 * 5. Optionally commits the change if `autoCommit` is `true`.
 *
 * If no changes are detected during deploy, the function exits early.
 *
 * @param {Object} options - The deployment options.
 * @param {ProposalType} options.proposalType - The type of change being proposed (e.g., deploy, upgrade).
 * @param {CdnParameters} options.cdn - Parameters for interacting with the CDN and associated governance.
 * @param {Function} options.executeChanges - A function that performs the actual upload and returns a `DeployResult`.
 *   Receives the generated proposal ID as input.
 * @param {boolean} options.autoCommit - If `true`, the function will also commit the change after submission.
 *
 * @returns {Promise<{proposalId: bigint}>} Resolves once the deployment and optional commit are complete.
 * Returns the proposal ID that was created.
 *
 * @throws {Error} If the SHA256 hash returned from `submitProposal` is `null` or `undefined`.
