Adds the five GEM event-subscription primitives the host needs to drive
the equipment's data-collection lifecycle (E30 §6.11):
S1F3/F4 selected status data
S1F11/F12 status variable namelist
S2F33/F34 define reports
S2F35/F36 link event reports
S2F37/F38 enable/disable events
Each is a one-line wrapper over the codegen builders + Connection's
send_request, surfacing the codegen-generated DefineReportEntry /
LinkEventEntry structs to callers behind a {id, [vids]} pair API.
This is the minimum surface a host needs to walk a fresh equipment
through "define report -> link CEID -> enable" and start receiving
S6F11 event reports — the same pattern the existing demo client does
inline. B3 lands the RCMD / recipe / job / terminal senders that
build on top.
