Typed values were quantized to the f32 grid before reaching the
entity (e.g. a length of 2000.8 committed as 2000.8020), worsening
with magnitude. The interaction point layer was all glam::Vec3 (f32).
Two-layer fix:
1. Coordinate backbone -> f64. last_point, last_cursor_world,
dyn_anchor, dyn_ref become DVec3; UcsXform transforms, parse_coord,
the ucs helper fns, dyn_resolve_point, the OTRACK typed-distance
paths, command-line coordinate entry and the coordinate readout all
compute in f64. Screen/GPU/alignment stays f32 (snap engine, render
geometry, projection, UCS-icon/viewcube drawing) with casts only at
those boundaries.
2. Per-command committed storage -> DVec3. on_point already received a
DVec3, but many command impls narrowed it back to f32 (let pt =
pt.as_vec3(); Vec<Vec3> fields) and re-widened at build, quantizing
the committed coordinate. Migrated PLINE, SPLINE, MLINE, LENGTHEN,
INSERT, 3D primitives, every dimension/leader/mleader, ray, revcloud,
wipeout, attdef, table, tolerance, array center, mview, plot_window,
plus the QDIM_PLACE handler and qdim_collect_points. Preview,
hit-test and rubber-band paths keep f32 at the boundary.
Hatch manual boundaries are left for a follow-up: HatchModel.boundary
is structurally Arc<Vec<[f32;2]>> and needs a model-level widen.

STRETCH picks its crossing window as two corner points. After the first
corner set last_point, Ortho/Polar constrained the opposite corner to an axis
through it, collapsing the window to a line and making selection impossible.
Add CadCommand::window_corner_pick(); STRETCH returns true for its two window
steps, and the viewport skips the ortho/polar (and OTRACK) lock for that point
in both the preview and commit paths — the corners are now free.
Also render the window like a normal box selection instead of a bare green
outline: add SelectionState::preview_box (a hit-test-free marquee), draw it
with the shared draw_marquee helper (green crossing fill + stroke), and drive
it from the command's new window_first_corner(). Cleared on command end.

Whole command/snap/grip/cursor chain now builds on f64 DVec3 end to end,
so picked points, snaps and grip drags stay precise at UTM-scale
coordinates instead of quantizing to ~0.5 m through f32.
- All ~80 command files migrated: draw (line/circle/arc/ellipse/shapes
in full f64; others via point methods), modify, annotate, insert, view,
inquiry, layers, groups, clipboard, layout.
- Entity apply_grip impls updated for GripApply::{Absolute,Translate}(DVec3).
- Construction sites (EntityTransform/CmdResult/DynAnchor) emit DVec3;
wire-preview boundaries cast to f32 only at the GPU edge.
- Modify/annotate commands keep internal Vec3 geometry where precision is
non-critical, casting at the DVec3 boundary; key draw commands store f64.
Builds clean (no warnings). Visual verification of crosshair/snap/grip at
extreme UTM zoom pending.

The Home tab was already titled "Draw"; rename the module to match:
folder modules/home → modules/draw, HomeModule → DrawModule, id "home"
→ "draw". The inner draw/ command folder is kept (modules::draw::draw).
Update build.rs PRIORITY ("home" → "draw") so the tab returns to the
front of the ribbon; registry.rs regenerates accordingly.
