Strip inline explanatory comments (comments are restricted to
technical-debt markers, #endif, and namespace-close trailers) from
HitLog.hpp, libSceConvertKeycode, libSceVoiceChat, libScePngEnc, and
the new hunk in libScePlayGo; add the missing #endif trailer comment
to HitLog.hpp's include guard. Rename the local helpers/params that
didn't match the naming convention: log_soft -> logSoft and
Readable -> readable (private free functions, camelCase), and
snake_case arguments (user_id, request_id, memory_address,
memory_size, output_info) to camelCase. NID export functions and
pre-existing upstream code (libScePlayGo's existing snake_case
parameters, PngEnc's vendored stb_image_write.h) are left untouched.

Init/terminate/handler/event exports are real no-ops. Session and
channel request exports return SCE_VOICE_CHAT error SIGNED_OUT, since
voice chat sessions cannot be established without a network backend.
Matches the offline-stub pattern already used by other online-service
PRX modules in this project.
