* feat: Add model compatibility check and memory estimation
This commit introduces a new feature to check if a given model is supported based on available device memory.
The change includes:
- A new `estimateKVCache` method that calculates the required memory for the model's KV cache. It uses GGUF metadata such as `block_count`, `head_count`, `key_length`, and `value_length` to perform the calculation.
- An `isModelSupported` method that combines the model file size and the estimated KV cache size to determine the total memory required. It then checks if any available device has sufficient free memory to load the model.
- An updated error message for the `version_backend` check to be more user-friendly, suggesting a stable internet connection as a potential solution for backend setup failures.
This functionality helps prevent the application from attempting to load models that would exceed the device's memory capacity, leading to more stable and predictable behavior.

* Extend this to available system RAM if GGML device is not available
* fix: Improve model metadata and memory checks
This commit refactors the logic for checking if a model is supported by a system's available memory.
**Key changes:**
- **Remote model support**: The `read_gguf_metadata` function can now fetch metadata from a remote URL by reading the file in chunks.
- **Improved KV cache size calculation**: The KV cache size is now estimated more accurately by using `attention.key_length` and `attention.value_length` from the GGUF metadata, with a fallback to `embedding_length`.
- **Granular memory check statuses**: The `isModelSupported` function now returns a more specific status (`'RED'`, `'YELLOW'`, `'GREEN'`) to indicate whether the model weights or the KV cache are too large for the available memory.
- **Consolidated logic**: The logic for checking local and remote models has been consolidated into a single `isModelSupported` function, improving code clarity and maintainability.
These changes provide more robust and informative model compatibility checks, especially for models hosted on remote servers.

* feat: Improve llamacpp server error reporting and model load stability
This commit introduces significant improvements to how the llamacpp server
process is managed and how its errors are reported.
Key changes:
- **Enhanced Error Reporting:** The llamacpp server's stdout and stderr
are now piped and captured. If the llamacpp process exits prematurely
or fails to start, its stderr output is captured and returned as a
`LlamacppError`. This provides much more specific and actionable
diagnostic information for users and developers.
- **Increased Model Load Timeout:** The `waitForModelLoad` timeout has
been increased from 30 seconds to 240 seconds (4 minutes). This
addresses issues where larger models or slower systems would
prematurely time out during the model loading phase.
- **API Secret Update:** The internal API secret for the llamacpp
extension has been updated from 'Jan' to 'JustAskNow'.
- **Version Bump:** The application version in `tauri.conf.json` has
been incremented to `0.6.901`.
* fix: should not spam load requests
* test: add test to cover the fix
* refactor: clean up
* test: add more test case
