Fix/rework async exceptions (#1130)
* cleanup imports and logs

* add BlockHandle type

* revert deps

* refactor: async error handling and future tracking improvements

- Update async procedures to use explicit raises annotation
- Modify TrackedFutures to handle futures with no raised exceptions
- Replace `asyncSpawn` with explicit future tracking
- Update test suites to use `unittest2`
- Standardize error handling across network and async components
- Remove deprecated error handling patterns

This commit introduces a more robust approach to async error handling and future management, improving type safety and reducing potential runtime errors.

* bump nim-serde

* remove asyncSpawn

* rework background downloads and prefetch

* imporove logging

* refactor: enhance async procedures with error handling and raise annotations

* misc cleanup

* misc

* refactor: implement allFinishedFailed to aggregate future results with success and failure tracking

* refactor: update error handling in reader procedures to raise ChunkerError and CancelledError

* refactor: improve error handling in wantListHandler and accountHandler procedures

* refactor: simplify LPStreamReadError creation by consolidating parameters

* refactor: enhance error handling in AsyncStreamWrapper to catch unexpected errors

* refactor: enhance error handling in advertiser and discovery loops to improve resilience

* misc

* refactor: improve code structure and readability

* remove cancellation from addSlotToQueue

* refactor: add assertion for unexpected errors in local store checks

* refactor: prevent tracking of finished futures and improve test assertions

* refactor: improve error handling in local store checks

* remove usage of msgDetail

* feat: add initial implementation of discovery engine and related components

* refactor: improve task scheduling logic by removing unnecessary break statement

* break after scheduling a task

* make taskHandler cancelable

* refactor: update async handlers to raise CancelledError

* refactor(advertiser): streamline error handling and improve task flow in advertise loops

* fix: correct spelling of "divisible" in error messages and comments

* refactor(discovery): simplify discovery task loop and improve error handling

* refactor(engine): filter peers before processing in cancelBlocks procedure
