Add cross-references between dynamic compression and pytest context saving docs

Link dynamic-tool-output-compression.md to pytest-context-saving.md as a
complementary token-saving method, and vice versa.

 Legacy Gemini connector truncation controls (`GEMINI_TOOL_OUTPUT_TRUNCATE_*` and backend `tool_output_truncate_*` extras) are deprecated but still functional:
 
-- When dynamic compression is **active**, legacy controls are accepted but marked inactive
-- When dynamic compression is **inactive**, legacy controls run through a compatibility path
-- Legacy session pytest compression toggles emit deprecation warnings

-## Migration from Legacy Features
-
-### From Pytest Output Compression
-
-The legacy `pytest_compression_enabled` toggle is deprecated. Migrate to dynamic compression:
-
-**Before:**
-```yaml
-session:
-  pytest_compression_enabled: true
-```
-
-**After:**
-```yaml
-dynamic_compression:
-  enabled: true
-  level: "balanced"
-```
-
-### From Backend Truncation
-
-Backend-specific truncation settings are deprecated:
-
-**Before:**
-```yaml
-backends:
-  gemini:
-    extra:
-      tool_output_truncate_chars: 10000
-```
-
-**After:**
-```yaml
-dynamic_compression:
-  enabled: true
-  level: "balanced"
-  min_bytes: 1024
