with a few serde directive we can get the same behaviour we had with
Option<Vec<Transport>> but only using Vec<Transport>
No need to change protocol specification
* Introduce Future Streams for Payments and Minting Proofs
Introduce Future Streams (`ProofStream`, `PaymentStream`) for Payments and
Proofs, an easier to use interface, async friendly, to interact for the mint
waiting for payments of mints for Bolt11 and Bolt12.

* feat(cdk): add Bolt12 mint quote subscription support
Extends subscription to handle Bolt12 payment method alongside existing Bolt11 support across wallet, mint, and CLI components.
* feat: refresh keysets
* fix(cdk): resolve keyset counter skipping index 0 in deterministic secret generation
- Modified Database::get_keyset_counter to return u32 instead of Option<u32>
- Added database migrations to increment existing keyset counters by 1
- Removed counter increment logic from wallet operations to use actual counter value
- Ensures deterministic secret generation starts from index 0 instead of skipping it
The primary purpose of this new crate is to have a common and shared codebase
for all SQL storage systems. It would force us to write standard SQL using best
practices for all databases.
This crate has been extracted from #878
* Split the database trait into read and transactions.
The transaction traits will encapsulate all database changes and also expect
READ-and-lock operations to read and lock records from the database for
exclusive access, thereby avoiding race conditions.
The Transaction trait expects a `rollback` operation on Drop unless the
transaction has been committed.
* fix: melt quote duplicate error
This change stops a second melt quote from being created
if there is an existing valid melt quote for an invoice already.
If the first melt quote has expired then we allow for a new melt quote to be created.

* feat(cli): enhance check-pending to reclaim proofs
The check-pending command now directly attempts to reclaim proofs that
are no longer pending, replacing the previous check-only behavior.
Changes:
- Replace check_all_pending_proofs with reclaim_unspent functionality
- Add more detailed feedback about pending proof status
- Update command description to reflect new reclaim behavior
- Improve error handling and status reporting
This change makes the command more useful by actively reclaiming
proofs rather than just checking their status.
* refactor: remove CheckSpendable command and check_spent module
The CheckSpendable command and its associated check_spent.rs module have been
removed as their functionality is redundant with the CheckPending command.
The bug comes with the SQLx-sqlite pool bug, where several connections are
created by default, but the `new` function takes care of that, fixing that bug
by making a single instance of the database.
If constructed directly, the pool would create several connections to the
database, which in most instances is fine, but with SQLite :memory: each
connection is entirely independent.
Also follow documentation to make sure that failed `acquire` will not end up
dropping connections by setting test_before_acquire to false
However, if your workload is sensitive to dropped connections such as using an in-memory
SQLite database with a pool size of 1, you can pretty easily ensure that a cancelled
`acquire()` call will never drop connections by tweaking your [`PoolOptions`]:
* Set [`test_before_acquire(false)`][PoolOptions::test_before_acquire]
* Never set [`before_acquire`][PoolOptions::before_acquire] or
[`after_connect`][PoolOptions::after_connect].
The main goal is to add a subscription to CDK Mint updates into the wallet.
This feature will be particularly useful for improving the code whenever loops
hit the mint server to check status changes.
The goal is to add an easy-to-use interface that will hide the fact that we're
connecting to WebSocket and subscribing to events. This will also hide the fact
that the CDK-mint server may not support WebSocket updates.
To be fully backward compatible, the HttpClientMethods traits have a new
method, `subscribe,` which will return an object that implements
`ActiveSubscription.`
In the primary implementation, there is a `SubscriptionClient` that will
attempt to connect through WebSocket and will fall to the HTTP-status pull and
sleep approach (the current approach), but upper stream code will receive
updates as if they come from a stream of updates through WebSocket. This
`SubscriptionClient` struct will also manage reconnections to WebSockets (with
automatic resubscriptions) and all the low-level stuff, providing an
easy-to-use interface and leaving the upper-level code with a nice interface
that is hard to misuse. When `ActiveSubscription` is dropped, it will
automatically unsubscribe.
Fixed bug with Default as described in https://github.com/cashubtc/cdk/pull/473#discussion_r1871032297
