feat: update Model Deck to 0.3.9

[0xTotoroX]

Summary

• update the existing Model Deck market entry and bundled script from 0.1.0 to 0.3.9
• discover selectable models from correlated model/list data and the visible official menu instead of a fixed model list
• add user-pinned models, a resizable model-name column, split-view composer targeting, Codex typography sync, verified Grok 4.5 reasoning levels, and polished Fast feedback
• retain global presets and route all configuration changes through the official menu

Publication contract

• standalone release: feat: release Model Deck 0.3.9 0xTotoroX/model-deck#2
• changed files: scripts/model-deck.js and index.json only
• standalone main, market script, and installed Codex++ script are byte-identical
• size: 111725 bytes
• SHA-256: 381362c2bffbc570a27a1879fd18b59235dd0bf7a7d42817bacf666c466a3fa5

Scope

This updates the existing model-deck entry. It does not modify codex-native-matrix-selector; Model Deck remains the hover-anchored matrix and reusable-preset workflow, and does not write React private state.

Verification

• standalone npm run check (88 tests, deterministic build, JS syntax)
• node --check scripts/model-deck.js
• JSON parse, schema shape, unique script IDs, manifest SHA, and git diff --check
• live injection on the exact app://-/index.html target with one API/root/style instance and a ready capability snapshot
• live panel screenshot checked at 522 x 202 with aligned rows and no clipping
