* Refactor payload structures to simplify API
Removed the 'provider', 'id', 'consumer' fields from protocol buffers, gRPC services, and related functions across various files to streamline the data model and align with the new authentication system based on cryptographic verification rather than string identifiers. This results in more efficient data handling and a reduction in unnecessary payload data, while enhancing security by making entity validation strictly cryptographic.
The changes affect agent-SDK interactions, CLI tools, and related services, ensuring only the necessary data (algorithm/data bytes, user keys, and hashes) is transmitted and processed. Consequently, the core computation algorithm and dataset handlers now rely on indexes derived from context to associate data with respective manifest entries, thus maintaining the ability to link to specific computation manifests without relying on explicit IDs in the payload. Additionally, refactored authentication methods now enforce role-based security seamlessly through metadata.
This approach enhances privacy by avoiding transmission of potentially sensitive strings over the network and by ensuring that only internal indices, not globally interpretable identifiers, are used to process computations.
Aligned with the broader architectural goal of simplifying and securing the platform's core services, this change paves the way for upcoming revisions to the authentication scheme that will further consolidate role-based security and improve system integrity.

Lastly, the main application now sets up two distinct command groups for 'agent' and 'manager', with respective commands organized under them, making the CLI tool's structure more intuitive for users.

Standardized the variable name for computation parameter across various service and middleware implementations to improve code consistency. This enhances readability and maintainability.
Additionally, tracing functionality has been removed completely, signifying a potential shift in the telemetry strategy or removal of an unused feature. The run command associated with cli package has also been deleted, suggesting a change in the CLI tool's capabilities or its command handling strategy.
The service interface's Run method definition and its implementations now align with the updated parameter naming, ensuring coherence throughout the codebase.
Removed files:
- The entire `tracing` package has been deleted.
- Removed the `cli/run.go` file, indicating the removal of the 'run' command from the CLI.
Please note that these changes may affect any existing workflows or systems that rely on the removed tracing capabilities or the CLI run command, and appropriate adjustments will need to be made to accommodate these updates.
Refer to internal documentation or release notes for migration paths or additional context.

* Fix race condition in agent service initialization
The commit fixes a race condition in the agent service initialization.
Previously, the `New` function in `agent/service.go` would start the state machine
goroutine before initializing the `sm` field. This could lead to a race condition
where the state machine would access uninitialized fields.
To fix this, the `New` function now takes a `context.Context` argument and passes it
to the `Start` method of the state machine. Additionally, a `sync.Mutex` has been
added to the `StateMachine` struct to ensure thread safety.
This commit addresses the race condition and ensures proper initialization of the agent service.

* Fix sending events when algorithms and datasets are received
This commit fixes a bug where events were not being sent when algorithms and datasets were received in the agent service. The bug was causing the events to not be triggered, leading to incorrect behavior. This commit adds the necessary code to send the events when algorithms and datasets are received, ensuring that the events are properly triggered.

* Fix bug: computation results not ready
The computation results were not being marked as ready,
resulting in an error when trying to access them.
This commit fixes the issue by adding a check for
the computation results before returning them.

* Fix bug in agent service and state
The commit fixes a bug in the agent service and state files.
Previously, the condition to check the state in the agent service
was incorrect. It was checking the state directly instead of
using the GetState() method. This has been fixed by using the
GetState() method to check the state.
Additionally, a new GetState() method has been added to the
StateMachine struct in the state file. This method retrieves
the current state by acquiring a lock and returning the state
value.
The changes have been tested and verified to resolve the bug
and improve the accuracy of state checking in the agent service.

* Fix bug in agent state machine
The bug in the agent state machine caused an error when attempting an invalid transition. This commit fixes the bug by properly locking and unlocking the state machine before and after transitioning to the next state. Additionally, the logger now correctly logs the current and next state during a valid transition.

* Fix race condition in state machine
The commit fixes a race condition in the state machine implementation in the `Start` method. The race condition occurs when multiple goroutines try to access and modify the state concurrently. To fix this, a mutex lock and unlock are added around the critical sections of code to ensure exclusive access to the state variable. This prevents race conditions and ensures the state transitions are executed correctly.

* Fix race condition in StateMachine.Start()
The StateMachine.Start() method was experiencing a race condition
when multiple events were being processed concurrently. This was
caused by not properly locking and unlocking the state machine
before and after updating the state. This commit fixes the issue
by adding proper locking and unlocking around the state update
operation. Additionally, the logging statement has been updated
to include the previous and next states for better debugging.
