Feature Request: Make chat conversation history available in context hooks

### Checks

- [x] I have searched [github.com/aws/amazon-q-developer-cli/issues](https://github.com/aws/amazon-q-developer-cli/issues?q=) and there are no duplicates of my issue
- [x] I have run `q doctor` in the affected terminal session
- [x] I have run `q restart` and replicated the issue again

### Operating system

macOS 15.4.1 (24E263)

### Expected behaviour

Context hooks should have access to the current conversation history, allowing scripts to process or utilize the ongoing chat content.

### Actual behaviour

Currently, context hooks don't have access to the conversation history, limiting their ability to be context-aware.

Example use case: a context hook that runs to extract information about the current conversation, such as user's input, documenting discussion and decisions made by user for future reference.

### Steps to reproduce

This is a feature request for new functionality rather than a bug. The requested feature would allow commands run from hooks to access and utilize the current conversation context.
