feat(assets): implant HUD icon set v0.1 — #795

13 SVG icons covering stance indicators (walk/careful/sprint/crouch),
status badges (health, perception), interaction prompts (talk/observe/
follow/examine), and inventory silhouettes (manifest, access token,
comm log).

All D-086 compliant: 1px stroke, #c8d0e0 chrome, round linecaps,
minimal anchor points, no icon fonts, runtime-replaceable via
ShaderMaterial. Sizes: 20×20 (stance/status), 16×16 (actions),
40×40 (inventory). Unblocks client #787.
