Reduced font sizes and used dominant-baseline="central" with y at
the vertical center so text is centered both horizontally and
vertically inside the box without overlapping the border.

When a symbol is mirrored, negate the horizontal drag delta and swap
the left/right handle identity so resizing matches the visual direction.
Also fixes spur handle resize with mirrored spurs.

- Remove tabs, single unified device list grouped by type
- Drop on empty space → places new symbol with device ID
- Drop on existing symbol → assigns the device ID as label
- Drop-target highlight shown when hovering over existing symbols
- Always sorted ascending by device type

Collision detection now mirrors spur trapezoid and induction arrow
vertices when the symbol is mirrored, matching the visual appearance.
Previously the collision polygon stayed unmirrored causing false
positives/misaligned collision zones.

Holding Shift while dragging locks movement to the dominant axis
(whichever has the larger delta from drag start). Works for both
single and multi-selection moves.

- Each ID entry now shows a small SVG icon of its symbol type
- Device type name shown as subtle suffix
- Search results sorted ascending by device type, then by ID
- Search also matches device type name

- Right-click context menu: "Hide" option to hide individual symbols
- "Show All Hidden" appears in context menu when anything is hidden
- Top visibility bar with toggle chips for each device group
- Hidden symbols are excluded from rendering, hit testing, and SVG export

- Single-element SVGs: id/label/transform directly on the element (no <g>)
- SVGs with <g> group (dpm, diverter): keep the group, put id/label on it
- Multi-child SVGs without group (beacon): wrap in <g> with id/label
- Programmatic shapes (induction, curved, spur): single <path> with id

- Add search filter to Devices tab in right dock
- Add IDs tab: flat list of unassigned device IDs, drag onto placed symbol to assign label
- Highlight drop target symbol with cyan glow during label drag
- Add labelDropTarget state and dropTarget theme entry

- Split collision.ts (707→549): extract distance.ts (pure math) and grid-snap.ts
- Fix curved conveyor/chute outline to match SVG viewBox geometry
- Draw curves programmatically with fixed 30px band width (no SVG stretching)
- Single resize handle for curves (was 2)
- Add .gitattributes for consistent line endings
- Make Vec2 type module-private
- Add mirror transform support in renderer
