A line whose FIRST point is a Tangent snap on a circle can't be fixed
until its direction is known, and a line tangent to TWO circles is their
common tangent — neither is resolvable at a single pick. A plain LINE
dropped the tangent object, so it drew a wrong line (TAN-TAN between two
circles).
Add an opt-in on_point_with_tangent hook (default ignores the tangent, so
every other command is byte-for-byte unchanged) and route the running
Tangent object through the point commit. LINE defers a first-point circle
tangent and resolves it on the next pick: against a second circle tangent
it picks the common tangent of the two circles (up to four — chosen by
the two cursor hits, so hovering selects inner/outer + side); against a
plain point it draws the tangent from that point to the circle.
last_point syncs to the resolved anchor. Common-tangent and point-tangent
math is f64 with perpendicularity unit tests.

Inserting a block piled every attribute at the origin: each AttributeEntity
was built from just tag + value with default geometry. Carry the full
AttributeDefinition through the attreq flow and build attributes with
AttributeEntity::from_definition, then apply the block's insertion transform
so each lands in WCS at its proper position / alignment / rotation.
Attributes are stored in world space, so moving the block must move them
too. The MOVE command already did (acadrust translate_insert); apply_grip
(grip-drag) and the Position X/Y/Z property edit now translate the
attributes by the same world delta so they no longer stay behind.
Rotate/scale/mirror of a block still don't carry the attributes — acadrust's
transform_insert has no attribute pass — tracked separately.

Double-clicking a block reference that has attributes, or running ATTEDIT
on one, now opens an editor dialog listing every attribute (tag + editable
value) with OK / Cancel. OK writes the values back to the block, with undo
and a repaint; Cancel discards. A block with no attributes still enters
in-place block edit (REFEDIT) on double-click as before. (#192)
ATTEDIT opens the dialog directly when a suitable block is already
selected; otherwise it runs the pick command and the dialog opens once a
block is chosen. This replaces the earlier command-line, per-attribute
prompt flow, which is removed along with its __ATTEDIT__ sentinel path and
the now-unused attedit_set_attrs trait hook; the ATTEDIT command is reduced
to a plain block picker.
The dialog is a tab-scoped in-canvas modal (Plan B): its working copy holds
a document-local handle, so closing that tab or switching away dismisses the
editor rather than risk applying edits to another tab's document.

- Delete src/modules/draw/modify/extend.rs (a 1-line placeholder with no
tool()/logic; `extend::` was referenced nowhere) and its `mod extend;`.
- Flatten single-file module dirs to the modern flat style:
src/command/mod.rs -> src/command.rs, src/snap/mod.rs -> src/snap.rs.
Parent `mod command;`/`mod snap;` are unchanged.
