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.
* WIP: Introduce a SignatoryManager service.
The SignatoryManager manager provides an API to interact with keysets, private
keys, and all key-related operations, offering segregation between the mint and
the most sensible part of the mind: the private keys.
Although the default signatory runs in memory, it is completely isolated from
the rest of the system and can only be communicated through the interface
offered by the signatory manager. Only messages can be sent from the mintd to
the Signatory trait through the Signatory Manager.
This pull request sets the foundation for eventually being able to run the
Signatory and all the key-related operations in a separate service, possibly in
a foreign service, to offload risks, as described in #476.
The Signatory manager is concurrent and deferred any mechanism needed to handle
concurrency to the Signatory trait.
* Fixed missing default feature for signatory
* Do not read keys from the DB
* Removed KeysDatabase Trait from MintDatabase
All Keys operations should be done through the signatory
* Make sure signatory has all the keys in memory
Drop also foreign constraints on sqlite
* Fix race condition
* Adding debug info to failing test
* Add `sleep` in test
* Fixed issue with active auth keyset
* Fixed dependency
* Move all keys and keysets to an ArcSwap.
Since the keys and keysets exist in RAM, most wrapping functions are infallible
and synchronous, improving performance and adding breaking API changes.
The signatory will provide this information on the boot and update when the
`rotate_keyset` is executed.
Todo: Implement a subscription key to reload the keys when the GRPC server
changes the keys. For the embedded mode, that makes no sense since there is a
single way to rotate keys, and that bit is already covered.
* Implementing https://github.com/cashubtc/nuts/pull/250
* Add CLI for cdk-signatory to spawn an external signatory
Add to the pipeline the external signatory
* Update tests
* Apply suggestions from code review

* Minor change
* Update proto buf to use the newest format
* Rename binary
* Add instrumentations
* Add more comments
* Use a single database for the signatory
Store all keys, even auth keys, in a single database. Leave the MintAuthDatabse
trait implementation for the CDK but not the signagtory
This commit also moves the cli mod to its own file
* Update dep
* Add `test_mint_keyset_gen` test

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].
