* fix: create new flows on invalid_grant errors
* chore: fix failing test
* chore: keep isOAuthError test function in sync with implementation
* test: add tests for OAuth error detection on invalid grant errors
* test: add tests for creating new flows when token expires
* test: add test for flow clean up prior to creation
* refactor: consolidate token expiration handling in FlowStateManager
- Removed the old token expiration checks and replaced them with a new method, `isTokenExpired`, to streamline the logic.
- Introduced `normalizeExpirationTimestamp` to handle timestamp normalization for both seconds and milliseconds.
- Updated tests to ensure proper functionality of flow management with token expiration scenarios.
* fix: conditionally setup cleanup handlers in FlowStateManager
- Updated the FlowStateManager constructor to only call setupCleanupHandlers if the ci parameter is not set, improving flexibility in flow management.
* chore: enhance OAuth token refresh logging
- Introduced a new method, `processRefreshResponse`, to streamline the processing of token refresh responses from the OAuth server.
- Improved logging to provide detailed information about token refresh operations, including whether new tokens were received and if the refresh token was rotated.
- Updated existing token handling logic to utilize the new method, ensuring consistency and clarity in token management.
* chore: enhance logging for MCP server reinitialization
- Updated the logging in the reinitMCPServer function to provide more detailed information about the response, including success status, OAuth requirements, presence of the OAuth URL, and the count of tools involved. This improves the clarity and usefulness of logs for debugging purposes.

* feat: Add conversation ID support to custom endpoint headers
- Add LIBRECHAT_CONVERSATION_ID to customUserVars when provided
- Pass conversation ID to header resolution for dynamic headers
- Add comprehensive test coverage
Enables custom endpoints to access conversation context using {{LIBRECHAT_CONVERSATION_ID}} placeholder.
* fix: filter out unresolved placeholders from headers (thanks @MrunmayS)
* feat: add support for request body placeholders in custom endpoint headers
- Add {{LIBRECHAT_BODY_*}} placeholders for conversationId, parentMessageId, messageId
- Update tests to reflect new body placeholder functionality
* refactor resolveHeaders
* style: minor styling cleanup
* fix: type error in unit test
* feat: add body to other endpoints
* feat: add body for mcp tool calls
* chore: remove changes that unnecessarily increase scope after clarification of requirements
* refactor: move http.ts to packages/api and have RequestBody intersect with Express request body
* refactor: processMCPEnv now uses single object argument pattern
* refactor: update processMCPEnv to use 'options' parameter and align types across MCP connection classes
* feat: enhance MCP connection handling with dynamic request headers to pass request body fields
