feat: rename search_and_replace tool to edit with new parameter structure

[hannesrudolph]

Summary

Renames the search_and_replace tool to edit with a new flat parameter structure (file_path, old_string, new_string, replace_all), replacing the old batch operations array. Keeps search_and_replace as a backward-compatible alias so models like MiniMax that reference it in includedTools continue to work without changes.

Changes

• New edit tool definition (src/core/prompts/tools/native-tools/edit.ts) with file_path, old_string, new_string, replace_all parameters
• New EditTool execution handler (src/core/tools/EditTool.ts) with replace_all support and uniqueness checking
• Alias system: Added search_and_replace: "edit" to TOOL_ALIASES — models with includedTools: ["search_and_replace"] (e.g., MiniMax) get the edit tool renamed as search_and_replace
• Parser updates: NativeToolCallParser.ts handles both "edit" and "search_and_replace" tool names with the new parameter structure
• Execution routing: presentAssistantMessage.ts routes both tool names to EditTool
• Alias resolution in validation: isToolAllowedForMode now resolves aliases when checking customTools, ensuring search_and_replace in includedTools correctly maps to edit
• Backward compat wrapper: SearchAndReplaceTool.ts reduced to a 2-line re-export from EditTool
• Types: Added "edit" to toolNames, "replace_all" to toolParamNames, updated NativeToolArgs
• Tests: 16 new EditTool tests covering basic replacement, replace_all, uniqueness errors, no-match errors, approval flow

Test Results

• 7 targeted test files: 105/105 passing
• Full src/ suite: 341 passed (29 pre-existing failures from missing @ai-sdk/amazon-bedrock — unrelated)
• packages/types: 170/170 passing

All previously flagged issues have been resolved. No new issues found in the latest commits (orphaned file deletion, XML false-positive fix, test stabilization for CI).

• Delete orphaned src/core/prompts/tools/native-tools/search_and_replace.ts (old parameter schema, no longer imported)
• containsXmlToolMarkup false-positive risk: "edit" in the tool-name list matches <editor>, <editable>, etc. after lowercasing -- fixed with hasTagReference boundary checking
