Affected Chromium adapters fail after selecting WebGPU even when packed renderer paths are forced. Use WebGL2 for the web app and let device limits select renderer tiers.\n\nRefs #788
The MText editor paints its own caret and is not a focusable widget, so
the command input keeps widget focus behind the dialog. It captures the
arrow itself, which routes the key through CommandLineArrowProbe instead
of ArrowKeyPressed — and that path only asked whether the command input
was focused, never whether an editor was open. Up and Down therefore
walked command history while the user was typing in MText.
Give the probe the same rule ArrowKeyPressed already applies: while the
editor is open the arrow moves its caret. The probe now carries the shift
state so a held Shift still extends the selection on this path.

solid_boolean() collects the selected solids straight out of
scene.selected, a HashSet, and then uses handles[0] and handles[1] as the
two operands. Set iteration order is arbitrary and can differ between
runs, so SUBTRACT — the one non-commutative operation of the three — could
cut either solid out of the other for the same selection.
Sort the pair by handle, so the solid created first is the body the other
is taken out of. UNION and INTERSECT are unaffected.
A circle of radius r tangent to a circle of radius r_i has its center at
r_i + r (external tangency) or |r_i - r| (internal). ttr_lc_candidates and
ttr_cc_candidates built that second distance as r_i - r and skipped the
combination when it came out negative, so every solution where the new
circle is the larger one and encloses an existing circle was dropped. TTR
over two circles could only ever return externally tangent results.
Only rho^2 reaches the algebra below, so taking the magnitude is enough,
which is how the tan-tan-tan path already computes it.
Fixes#814
The embedded-expression rescan in eval_to_string tries every substring, so
any identifier the evaluator knows is also recognised in the middle of
ordinary text. Because `pi` needs no arguments it resolves anywhere it
appears, and names typed into property or command fields were rewritten:
`ASPIRATORE` came back as `AS3.141592653589793RATORE`.
Require a candidate whose first or last token is an identifier to start,
respectively end, on a word boundary. Leading and trailing numbers stay
unrestricted so mixed input such as `def10*10abc` still evaluates.
Fixes#809
PluginManager::broadcast_notification was fanning out host notifications to every loaded plugin. Only V4 plugin processes can receive host->plugin notifications; V2/V3 plugins correctly rejected them with notify_plugin requires V4 protocol.
Add PluginProcess::is_v4() and skip non-V4 plugins in broadcast_notification so V4 document snapshot notifications only go to V4-capable plugins. Fixes repeated console errors for Example, Land Survey and V2 Compat.
