* assembly(feat): ground first parts and drag free joint chains
Ground the first top-level part when it is created and let face dragging reposition free occurrences or any member of a floating joint chain in one undo step. Preserve exact repeated-placement frames, joint values, modifier selection and Escape cancellation. Keep the accumulated fixture, viewport layout and documentation integration fixes from the existing PR.

* assembly(fix): update movable fixtures for first-part grounding
Accept the documented grounded override in component creation, explicitly free movement fixtures, and keep linked clipboard pastes movable even in an empty document. Cover first and reused linked pastes, default insertion grounding, and single-step undo in the existing link tests.

* assembly(test): keep the motion-cost crank free
Unground the first component in the document-level joint-face measurement fixture so its motion samples can rotate after first-part grounding. Preserve the rotation and shared-measurement assertions that caught the Linux CI failure.

* assembly(test): free the frame placement fixture
Create the frame-member placement fixture ungrounded before moving it above its root sketch. Keep its world-space member assertions while respecting first-part grounding in the frame tests added on main.

A design built over MCP is many small commands, and each one did work over the
whole design, so building or showing a 1,300-body design took minutes:
- moved components were transformed and meshed again after every change; world_state
now reuses each placed body whose definition and placement are unchanged
- next_d_name searched the design once per candidate number
- Document::eval evaluated every parameter for every expression; now only when the
expression names one
- param_rows' used_by was quadratic; the desktop no longer gathers completions on every
change while no text box has focus
solidcraft-cli bench-agent builds a generated ~1,300-body bicycle command by command
and times it (241 s -> 16 s here). Eval output is unchanged apart from timings.
