* feat(commands): find the Elliptical Marquee by 'ellipse' or 'marquee' (#5060)
The Elliptical and Single Row/Column Marquee are options of select.rect
("ellipse":true, "line"), but the command-list filters only looked at
the id and the label ("Rectangular Selection"), so 'ellipse' and
'marquee' found nothing.
Commands can now carry search keywords. command.list / engine.commands
rows include them as "keywords", and the three filters (CLI commands
--filter, the engine.commands RPC and the MCP command_list) share one
matcher over id, label and keywords. select.rect gets the Photoshop
marquee names as keywords.
* Command list replies: document the optional keywords key
The reply-shape test from #3684 pins the exact keys of each row; select.rect
now also carries keywords, so the test and docs/control-protocol.md allow
that one optional string.
