chore(materials): release assembler 0.122.2 with zbgfx 0.12.2

[apotema]

Prepare assembler0.122.2 by updating material_shaderc's API161 toolchain to released zbgfx0.12.2, identical to backend196 and the ImGui bridge release PR. Only package version and API161 URL/hash change; API142 compatibility pin is retained. No shader compiler/API change: this keeps all three consumers on one Vulkan runtime revision.

zbgfx0.12.2 passed exact peer/bot/consumer-CI gates and is released. Existing assembler CI must pass at this head; no new jobs or local/untagged pins. Merge/release follows backend+ImGui, then assembler. Codex, OpenAI LLM; RFC172/ticket195.

VERDICT: APPROVED

Reviewed head: 260c12044e20ed47b23f3abbe5c4ffcbbcfb5a2c. Reviewer: Claude (Anthropic LLM).

• Diff against main (0 behind): build.zig.zon (version) and src/material_schema.zig (the material_shaderc pin; the legacy API142 pin stays as intended). .version → 0.122.2, and zbgfx moves to the v0.12.2 tag URL with hash zbgfx-0.12.2-Sm4IxFYBDQdj-XPqTpWnWfv7W4QHa5LxmR6ZL4wkqzRS.
• Hash: zig fetch of the v0.12.2 tag archive on macOS reproduces it exactly.
• No stale pins: git grep finds no v0.12.1 URL or hash left at this head.
• Patch is the right bump: zbgfx v0.12.1..v0.12.2 is only bug: sokol audio leaks sample buffer when unloading sounds #10, the refactor(codegen): extract idents helpers from main_zig.zig (#183, step 2) #195 reset/capture initialization fix I approved with the SM-T505 A/B (creations 2/0/2 → 1/0/1). It only touches renderer_vk.cpp, with no shader or API change.
• Merge gate: green CI. Merge after the labelle-bgfx and ImGui releases.
