Implement browser control agents using the Gemini 2.5 Computer Use Preview
model (gemini-2.5-computer-use-preview-10-2025) with Kernel's Computer
Controls API.

## TypeScript Template Changes
- Refactored index.ts to use modular architecture
- Added loop.ts: Core sampling loop implementing Google's agent pattern
- Added session.ts: KernelBrowserSession for browser lifecycle management
- Added tools/computer.ts: Maps Gemini actions to Kernel Computer Controls
- Added tools/types/gemini.ts: Type definitions for Gemini actions
- Updated package.json: @google/genai ^1.0.0

## Python Template (New)
- main.py: Action handler with KernelBrowserSession context manager
- loop.py: Async sampling loop matching TypeScript implementation
- session.py: Async context manager for browser lifecycle
- tools/computer.py: Gemini-to-Kernel action mapping
- tools/types.py: Dataclasses and enums for Gemini actions

## Integration Pattern
Both templates implement Google's recommended Computer Use agent loop:
1. Send request with computerUse tool configured
2. Receive function_call from model (click_at, type_text_at, navigate, etc.)
3. Execute via Kernel Computer Controls API
4. Capture screenshot + URL, send as function_response
5. Loop until task complete

## Key Features
- Coordinate denormalization (Gemini 0-1000 → Kernel pixels)
- Screenshot pruning to manage context size
- Optional replay recording for debugging
- Safety decision handling (auto-acknowledge for automation)

Tested: Both templates successfully navigate to Wikipedia and extract
the featured article title.

- Introduced `getSystemPrompt` function in both TypeScript and Python templates to generate the system prompt dynamically, including the current date.
- Updated the sampling loop to utilize the new function, improving code readability and maintainability.

- Corrected the Google AI API key link in both Python and TypeScript README files.
- Updated the Kernel documentation link to point to the Computer Controls section for better clarity.

- Added descriptions for `open_web_browser` and `search` actions in both Python and TypeScript README files to enhance clarity on browser functionalities.

…uterTool

- Eliminated the `screenshot` attribute from the `ToolResult` class and its usage in the `ComputerTool` class, streamlining the data structure and focusing on the `base64_image` representation.

Resolves conflicts by including both Gemini and Yutori computer use
templates for Python.

- Added an `error` field to the `QueryOutput` type in both Python and TypeScript templates to capture and return error messages.
- Updated the `sampling_loop` function in both languages to handle exceptions and store error messages, improving feedback during execution.
- Adjusted return values to include the new `error` field, ensuring consistent output structure across templates.

refactor(loop): simplify Gemini client initialization in sampling loop

- Removed environment variable dependencies from the Gemini client initialization in the `sampling_loop` function, streamlining the setup process.
- The client is now instantiated solely with the API key, enhancing clarity and reducing complexity in the code.

…ns dynamically

- Updated the `PREDEFINED_COMPUTER_USE_FUNCTIONS` in both Python and TypeScript templates to derive directly from the `GeminiAction` enum, ensuring consistency and reducing maintenance overhead when adding new actions.

…ion option for python

- Added error logging in the TypeScript template to print error messages when present in the result.
- Implemented a local execution block in the Python template to run tests directly, including error handling and logging for better debugging feedback.
