feat(bforge): forge serious Greek game assets, units, and weapons

[lxsolutions]

What changed

This draft contains reusable bforge work discovered while producing Spike's serious Greek visual pass:

• Adds bforge audit for existing model and raster assets, including progression-family reports and contact sheets.
• Expands deterministic olive/cypress tree generation.
• Adds char.outfit Greek delver, hoplite, peltast, bone-stalker, bone-oracle, Strategos, Warlock, toxotes, and hypaspist silhouettes.
• Gives toxotes a headwrap, quiver and arrows, asymmetrical pauldron, bracers, greaves, and light pteruges.
• Gives hypaspists a layered cuirass/lames, heavy pteruges, dual pauldrons, cheek guards, and a taller restrained crest.
• Adds char.skeleton, grounded creature.hound and creature.scarab, and the arch.civic_hall Greek mine/polis Town Centre.
• Adds prop.crossbow, with four real construction tiers for progressive FPS/RPG armories.
• Adds prop.bow, a grip-centred laminated recurve with reflexed limbs, bronze collars, taut drawn string, and optional nocked arrow/fletching.
• Makes bone-parented prop rotations valid in strict checks while preserving clean-scale requirements.
• Fixes export metadata budgets and discards Blender's glTF armature-display helper during import.
• Regenerates the 116-operation catalog and reference documentation.

Why

Spike's production assets exposed gaps that one-off Blender scripts would only hide. Generic/reused bodies made RTS soldiers, late-wave enemies, and the hero feel interchangeable. The new character, creature, architecture, foliage, bow, and crossbow operations solve those production problems as reusable bforge primitives rather than Spike-only mesh edits.

User and developer impact

Agents can now forge a serious, role-distinct Greek commander, archer, heavy guard, occult caster, grounded creature, RTS civic centre, hand bow, or progressive first-person crossbow armory; rig and animate applicable assets; export them; and audit the result through one documented workflow. Existing recipes remain compatible and every new operation/style is opt-in.

Validation

• Full Blender-backed suite: 76 tests passed across three independently bounded shards (29 + 21 + 26)
• Focused new tests verify distinct riggable toxotes/hypaspist geometry and the bow's grip pivot, drawn string, nocked arrow, bounds, materials, and 1,800-triangle ceiling
• Strict Spike Spearman, Archer, and Warden exports: zero warnings, 2,447–2,968 triangles
• Spike consumer suite: 50 tests passed
• Spike TypeScript typecheck and production build passed
• Desktop and 390x844 mobile Hero/Commander browser QA passed with zero console warnings/errors
