- Line 1008: Update the startup flow around main and startServer so the
effective --api --port override is used by net.Listen instead of a stale
reloaded configuration value. Pass the resolved port into startServer or persist
it in Config, ensuring the reported and bound ports remain consistent.

- Around line 42-44: Remove the unconditional parseMCPConfig call from the
shared API configuration parsing flow, and invoke MCP validation only from the
API server startup path that actually starts MCP. Ensure admin, ingestor,
syncer, and migration initialization can proceed without validating MCP
settings.

Preserve the API --port override when starting the server.
GetAPIServerConfig() returns an APIServerConfig value, so the assignment in main changes only a local copy. startServer(ctx) reloads the original configuration and uses its HTTPPort for net.Listen. Therefore, --api --port 9999 can report port 9999 while binding the configured port. Pass the effective port to startServer, or persist the override in Config.

Do not validate MCP configuration for processes that do not start MCP.
server.Init loads the shared API configuration for admin, ingestor, syncer, and migration modes. Therefore, RAGFLOW_MCP_PORT=invalid makes each of these startup paths fail before its work begins. TestParseArgsKeepsMCPOutOfCLI checks argument parsing only; it does not cover full process initialization.
Move MCP parsing to the API startup path, or separate it from shared API server configuration parsing.

129 upstream commits. One conflict, internal/handler/mcp_server.go: infiniflow#20011 renamed MCPListChats to mcpListChats and moved it. Resolved to upstream's file with this branch's one change carried over, the two empty id and name arguments in its ChatService.ListChats call. go vet passes on internal/dao, internal/service and internal/handler. Their tests pass, 249, 1155 and 581, including TestChatDAOListExactIDAndNameFilters and TestChatServiceListChatsExactFilters.

MCP settings now use YAML and environment variables, with shared handlers for both transports. This removes duplicate startup code and protects local requests and API keys.
