Upgrades: - bdk_wallet: 2.0.0 -> 2.3.0 - bdk_esplora: 0.22.0 -> 0.22.1 Notable changes in bdk_wallet 2.1.0-2.3.0: - BIP-389 two-path multipath descriptor support - TxBuilder::exclude_unconfirmed and exclude_below_confirmations - Wallet events on apply_update (2.2.0) - apply_block_events and apply_block_connected_to_events (2.3.0) - build_fee_bump fix for missing parent txid (2.3.0) - signer module deprecated (2.2.0)
Adds support for creating a wallet from a BIP-389 two-path multipath descriptor. This allows users to specify a single descriptor with both receive and change paths (e.g. wpkh(xpub.../<0;1>/*)) instead of providing two separate descriptors. Wraps BdkWallet::create_from_two_path_descriptor introduced in bdk_wallet 2.1.0.
Adds two new methods to TxBuilder for filtering UTXOs by confirmation status: - exclude_below_confirmations(min_confirms): excludes outpoints from transactions with fewer than min_confirms confirmations - exclude_unconfirmed(): shorthand for exclude_below_confirmations(1) These methods mirror the BDK wallet 2.1.0 API and compute the excluded set based on the wallet's current chain tip height.

bdk_wallet 2.2.0 deprecated the signer module (including SignOptions) in favor of bitcoin::psbt::Psbt::sign(). However, Wallet::sign still requires SignOptions internally, so we add #[allow(deprecated)] until BDK provides a full migration path. Added documentation noting the deprecation status and migration plan.
Comprehensive guide covering architecture, build/test instructions, CI pipeline, dependency management, coding conventions, and known issues. Useful for both human contributors and AI agents working on the codebase.

Instead of reimplementing the UTXO filtering logic locally, store the min_confirmations parameter and pass it to BDK's TxBuilder in finish(). This follows the same delegation pattern used by all other builder methods.
