The renderer shares one set of wire GPU buffers per wire_content_id
across every pane and viewport slot. Every geometry edit mints a new
content id, so every edit builds a new set -- and the old one stayed in
wire_buffer_cache until the map exceeded sixteen entries.
Sixteen entries is a sane bound for small drawings and fatal for large
ones. The policy counted entries, not bytes. On the reproducer a single
set is most of the card: the VRAM trace shows 572 MiB baseline rising to
1871 MiB on a 2048 MiB GT 1030. The second set has nowhere to go, so the
first edit after opening exhausts VRAM. The perf log shows exactly that
-- two `shared-fullupload` lines, an edit, then the process dies.
Evict on every miss instead of at a count threshold, and do it before
building the replacement rather than after, so the old allocation is
released while the new one is still being sized. Dropping this slot's own
handles first is what lets the retain see the superseded entry as
garbage; a pane still drawing that content keeps its own clone and its
strong count stays above one, so shared geometry is never pulled out
from under a live viewport.
The trade is that returning to a previous content id -- undo, mostly --
now rebuilds instead of hitting a warm entry. On a card where the
alternative is dying, that is the right way round.
Adds a PERF line reporting evicted and retained entry counts, so the
policy can be watched rather than assumed.

Implement the AutoCAD compatible HATCHTOBACK (HB) command and enhance the interactive DRAWORDER command pipeline with comprehensive verb selection and viewport entity picking.
Key implementations and architectural details:
1. HATCHTOBACK command execution
* Isolates entities belonging to the active layout block record or global space.
* Filters out entities residing on locked layers using an efficient hash set lookup.
* Records targeted delta undo operations on SortEntitiesTable objects (~100 bytes) rather than snapshotting full document structures.
* Performs granular draw depth cache invalidation via Scene::invalidate_draw_depth, preserving existing geometry tessellations and spatial indices.
* Emits localized user notifications when no qualifying hatch entities are found.
2. Interactive DrawOrderCommand state machine
* Supports preselected entities as well as interactive on demand selection gathering.
* Implements subverb selection supporting single character shortcuts (A for Above, U for Under, F for Front, B for Back) and case insensitive keyword parsing.
* Enables interactive reference object picking directly in the viewport via needs_entity_pick and on_entity_pick callbacks.
* Supports hexadecimal handle specification directly from the command line interface.
3. Ecosystem and system integration
* Bumps DEFAULT_ALIASES_VERSION from 2 to 3 to register the HB alias while preserving existing user overrides.
* Integrates HATCHTOBACK and HB into dynamic autocomplete registries.
* Adds localized message strings across all 20 Fluent translation catalogs.
* Corrects hatch boundary serialization flags to ensure outermost boundary rings consistently carry the external attribute.
Complete missing keys in the existing translations and add selectable Spanish, Brazilian Portuguese, Arabic, and Japanese resources.\n\nThe large compatibility catalogs for the new locales remain in progress.
- preserve command history colors after reopening
- remove collapsed command bar residue and split the unsaved prompt
- read system text when the drawing clipboard is empty
