Add undo and redo ops to the headless server (synchronous via update()).
Combined with select, the modify commands MOVE/COPY work through the
existing dispatcher — "select type=Line" then run("MOVE 0,0 10,0")
translates the selection. ocs.py gains undo()/redo().

Add a select op that sets the document selection (by hex handles from
query, or by type/layer, or clear). Selection drives modify commands, so
an agent can query → select → run("ERASE") to act on specific entities.
Completes the modify half of the act/observe loop. ocs.py gains select().

Add a query op to the headless server: list entities with handle, type,
layer and basic geometry (Line start/end, Circle/Arc centre+radius, Point
location), filtered by type and/or layer and capped by limit. Closes the
observe half of an agent's act/observe loop. ocs.py gains ocs.query().

run now feeds coordinate tokens to interactive tools: "LINE 0,0 10,10"
starts the tool, feeds the points, and terminates as if Enter were
pressed — creating real geometry through the existing command system. The
headless session also leaves the welcome (Start) tab so drawing commands
aren'\''t blocked. Verified end-to-end: LINE/CIRCLE create entities that
save and reopen.

Add an external automation API (issue #29 / #100 track 2): `OpenCADStudio
--serve` runs without a GUI and is driven over a line-based JSON protocol
on stdin/stdout — open / new / run / entities / save. State persists
across requests so a script or AI agent can act, observe, and act again.
`run` drives the app's existing command system rather than a separate
binding, so coverage grows with the app; synchronous commands apply now,
pick-based interactive ones come once coordinate feeding is wired. Ships
a ~100-line example ocs.py client over the same protocol — no FFI to
maintain. Headless works because the app already constructs and dispatches
GUI-less in tests.
