Improve error message formatting by replacing semicolon separators with newlines for better readability

- Detect and unwrap responses wrapped in 'assistant: [{"type": "text", "text": "..."}]' format
- Use extracted text for response content instead of raw accumulated text
- Fix variable scoping issue with tool_match variable
- Update token counting to use final_text when available

Instead of collecting all chunks and sending a modified response:
- Stream chunks normally as they come (with deltas like before)
- Only at the END, if tool call pattern detected, send additional chunk with tool_calls
- Then send final chunk with usage statistics

This preserves the original streaming behavior while adding tool call detection.

When the model returns a response in the format:
assistant: [{'type': 'text', 'text': '...'}]
but without a tool call, extract just the text content
instead of returning the raw wrapper format.

The model returns literal \n (backslash-n) instead of actual newlines.
This breaks JSON parsing because {\n is not valid JSON syntax.
Use codecs.decode with 'unicode_escape' to convert escape sequences
to actual characters before parsing.

- Log accumulated response text (first 500 and last 200 chars)
- Log extracted tool JSON with length and byte details
- Log ASCII codes for first 20 chars to detect encoding issues
- Log JSON parse errors with position details
- Log success/failure of JSON parsing attempts

- Use brace counting for robust JSON extraction
- Try JSON first, then fix common issues (single quotes, trailing commas)
- Extract final assistant text using regex after tool JSON
- Remove complex nested parsing that was failing with escaped quotes

- Models may return single quotes instead of double quotes
- Fall back to ast.literal_eval when JSON parsing fails
- Handle both JSON and Python-style literals in streaming responses

- Detect tool calls in accumulated streaming text after all chunks received
- Parse nested 'assistant: [...]' format with tool calls inside
- Parse simple 'tool: {...}' format
- Convert detected tool calls to OpenAI-compatible format
- Send tool_calls in first chunk, then final assistant text
- Proper handling of finish_reason in final chunk

- Detect when entire response is wrapped in 'assistant: [...]'
- Parse nested 'tool: {...}' inside the assistant text
- Extract final assistant text from nested structure
- Handle multi-line JSON content with proper brace counting
- More robust parsing for complex nested formats

- Detect '"content": "..." } assistant: [...]' pattern
- Extract tool content and convert to write action
- Extract assistant text from JSON array
- Handle multi-line content with newlines
- More robust tool call detection for various text formats

- Detect 'tool: {...}' pattern in Google model text responses
- Parse and convert to OpenAI-compatible tool_calls format
- Extract assistant text from 'assistant: [...]' format if present
- Handle both 'action' and 'name' fields for tool identification
- Convert arguments to JSON string for OpenAI compatibility

This fixes issues where models return tool calls as text instead of
using proper function_call attributes.

- Google provider now yields raw chunk objects instead of pre-formatted SSE bytes
- The handlers.py handles the conversion to OpenAI-compatible format
- This fixes the issue where clients weren't receiving streaming responses

Note: Server must be restarted to pick up this change

- Import count_messages_tokens from utils module
- Fixes 'name count_messages_tokens is not defined' error in Google streaming handler

- Add 'condensation' section to providers.json for specifying dedicated provider/model
- Add CondensationConfig model to config.py
- Add _load_condensation() and get_condensation() methods
- Update ContextManager to use dedicated condensation handler when configured
- Update handlers to pass condensation config to ContextManager
- Allows using smaller/faster model for context condensation operations

This addresses the issue where conversational and semantic condensation
methods were using the same model as the main request, which was
inefficient. Now users can configure a dedicated provider and model
for condensation operations, typically using a smaller/faster model to reduce
costs and improve performance.

- Fixes issue where tool calls were returned as text instead of tool_calls structure

- Add logic to detect and parse tool calls from text content

- Handles both Google-style (action) and OpenAI-style (function/name) tool calls
- Clears response_text when tool_calls are detected
