feat(core): implement tool preselection to reduce context size

- Created ToolPreselectionService using the classifier model to select only relevant tools for a given prompt. - Integrated pre-selection into LocalAgentExecutor and GeminiClient to automatically filter the tool registry. - Added `general.toolPreselection` toggle in configuration (enabled by default). - Added comprehensive unit tests and an E2E scenario confirming accurate tool reduction without loss of function. - Fixes #17113
