Note
Medium Risk
Third-party HTTP stack changes can alter parsing, redirects, and transfer encoding for all Robot API traffic, though application code is unchanged.
Overview
Replaces the vendored single-header cpp-httplib at
3rdparty/urcl_3rdparty/httplib/httplib.hwith 0.49.0 (no other repo files or build wiring called out in the PR).Upstream changes in this drop affect HTTP behavior used indirectly by
DashboardClientImplX(httplib::Clientfor Robot API GET/POST/PUT and multipart program upload). Notable shifts in the library include stricter RFC 9110 header handling (values are no longer auto percent-decoded), more permissive chunked body termination, optional WebSocket APIs, and a compile-time requirement for Windows 10+ when building on Windows.Reviewers should sanity-check dashboard connectivity, redirects, timeouts, and program upload/download against a controller after the bump.
