* refactor: reorganize browser utility functions and improve buffer handling
* fix: harden protobuf deserialization and clean up code
* refactor: simplify data handling in GroupCipher and SenderKey classes
* fix: Ensure consistent Buffer hydration and remove redundant code
* refactor: update decodeAndHydrate calls to use proto types for improved type safety
* fix: handle invalid signatureKeyPublic types in sender-key-state
- added extra check to ensure signatureKeyPublic is either a base64 string or a Buffer
- fallback to empty buffer when unexpected object type is received
- prevents ERR_INVALID_ARG_TYPE error in Buffer.from
* adjusted based on @jlucaso1 recommmendation
* fix: handle chain key objects for skmsg group message decryption
previously, some sender chain keys were stored or retrieved as plain objects
(e.g. { '0': 85, '1': 100, ... }) instead of Buffers. this caused
"ERR_INVALID_ARG_TYPE" during initial decryption of skmsg group messages.
this fixes any chain key object is converted to a proper Buffer
before being passed to SenderChainKey.
* fix: add more robust checks and fallbacks
* feat: async cache

* fix: linting issues

* hacky fix(sender-key-state): normalize signing pubkey as Buffer with 0x05 prefix
a little hacky fix that ensures getSigningKeyPublic always returns a proper Buffer to satisfy libsignal.
adds a fallback to prepend 0x05 when only a 32-byte key is present, avoiding
"Invalid public key" errors and TS type issues around Uint8Array vs Buffer.
* mutex reimplementation

* Add cleanup for expired sender key mutexes
Introduces a mechanism to periodically clean up unused sender key mutexes in addTransactionCapability, reducing memory usage by removing mutexes that have not been used for over an hour and are not locked. A timer is started when the first mutex is created, and cleanup runs every 30 minutes.
* Update auth-utils.ts
* Refactor Signal key transaction usage
Introduces a local variable for parsed Signal keys in libsignal.ts to avoid repeated type assertions and improve code clarity.
* Refactor transaction handling for key operations
Introduces per-entity mutexes and passes key identifiers to transaction calls for finer-grained concurrency control in Signal key storage and socket operations. Updates transaction signatures and usage across Signal, Socket, and Utils modules to improve atomicity and performance, especially for system and sync messages.
* Improve SignalKeyStore transaction handling
Refactored transaction logic in SignalKeyStore to add commit retries, cleanup of transaction state, and improved mutex management for sender keys. Enhanced validation and batching for pre-key deletions and updates, improving concurrency and reliability.
* Replace custom mutex cleanup with LRU cache
Switched from manual mutex cleanup logic to using the lru-cache package for managing mutexes in addTransactionCapability. This simplifies resource management and ensures expired mutexes are automatically purged. Added lru-cache as a dependency.
* Lint fix
* Update src/Signal/libsignal.ts
* Update libsignal.ts
