🤖 feat: Streamline Endpoints to Agent Framework (#8013)

* refactor(buildEndpointOption): Improve error logging in middleware, consolidate `isAgents` builder logic, remove adding `modelsConfig` to `endpointOption`

* refactor: parameter extraction and organization in agent services, minimize redundancy of shared fields across objects, make clear distinction of parameters processed uniquely by LibreChat vs LLM Provider Configs

* refactor(createPayload): streamline all endpoints to agent route

* fix: add `modelLabel` to response sender options for agent initialization

* chore: correct log message context in EditController abort controller cleanup

* chore: remove unused abortRequest hook

* chore: remove unused addToCache module and its dependencies

* refactor: remove AskController and related routes, update endpoint URLs (now all streamlined to agents route)

* chore: remove unused bedrock route and its related imports

* refactor: simplify response sender logic for Google endpoint

* chore: add `modelDisplayLabel` handling for agents endpoint

* feat: add file search capability to ephemeral agents, update code interpreter selection based of file upload, consolidate main upload menu for all endpoints

* feat: implement useToolToggle hook for managing tool toggle state, refactor CodeInterpreter and WebSearch components to utilize new hook

* feat: add ToolsDropdown component to BadgeRow for enhanced tool options

* feat: introduce BadgeRowContext and BadgeRowProvider for managing conversation state, refactor related components to utilize context

* feat: implement useMCPSelect hook for managing MCP selection state, refactor MCPSelect component to utilize new hook

* feat: enhance BadgeRowContext with MCPSelect and tool toggle functionality, refactor related components to utilize updated context and hooks

* refactor: streamline useToolToggle hook by integrating setEphemeralAgent directly into toggle logic and removing redundant setValue function

* refactor: consolidate codeApiKeyForm and searchApiKeyForm from CodeInterpreter and WebSearch to utilize new context properties

* refactor: update CheckboxButton to support controlled state and enhance ToolsDropdown with permission-based toggles for web search and code interpreter

* refactor: conditionally render CheckboxButton in CodeInterpreter and WebSearch components for improved UI responsiveness

* chore: add jotai dependency to package.json and package-lock.json

* chore: update brace-expansion package to version 2.0.2 in package-lock.json due to CVE-2025-5889

* Revert "chore: add jotai dependency to package.json and package-lock.json"

This reverts commit 69b6997396.

* refactor: add pinning functionality to CodeInterpreter and WebSearch components, and enhance ToolsDropdown with pin toggle for web search and code interpreter

* chore: move MCPIcon to correct location, remove duplicate

* fix: update MCP import to use type-only import from librechat-data-provider

* feat: implement MCPSubMenu component and integrate pinning functionality into ToolsDropdown

* fix: cycling to submenu by using parent menu context

* feat: add FileSearch component and integrate it into BadgeRow and ToolsDropdown

* chore: import order

* chore: remove agent specific logic that would block functionality for streamlined endpoints

* chore: linting for `createContextHandlers`

* chore: ensure ToolsDropdown doesn't show up for agents

* chore: ensure tool resource is selected when dragged to UI

* chore: update file search behavior to simulate legacy functionality

* feat: ToolDialogs with multiple trigger references, add settings to tool dropdown

* refactor: simplify web search and code interpreter settings checks

* chore: simplify local storage key for pinned state in useToolToggle

* refactor: reinstate agent check in AttachFileChat component, as individual providers will ahve different file configurations

* ci: increase timeout for MongoDB connection in Agent tests
