NoGoZones 0.14.0: admin-marked no-go zones for CS2

CounterStrikeSharp 1.0.375 plugin. Admins mark 4 points with their crosshair (native
Trace.TraceEndShape), preview the box with env_beam lines, and confirm it into a per-map
zone file. Points in a near-vertical plane make a wall zone, turned to match the face.

- Players are kept out by a per-tick movement block (swept against the zone box grown by
  the player's hull), since CSS can't give a spawned entity custom-size collision.
- Wall zones are drawn as a border with horizontal fill lines (optionally scrolling and
  pulsing) and a beam-built no-entry sign; floor zones as a rectangle with an X.
- Commands: css_zone_start/color/mark/height/confirm/cancel, css_zone_list/near/remove/
  active/reload, all gated on @css/root.
- release.sh builds from the committed source and publishes NoGoZones-<tag>.tar.gz.
