docs(modules): add taste community bundle

[michaeljabbour]

Add taste community bundle to MODULES.md

This PR adds amplifier-bundle-taste, an Amplifier-native adaptation of Leonxlnx/taste-skill (MIT), which provides anti-slop frontend design discipline: named hard-bans on LLM UI defaults (Inter font, purple-blue gradients, centered heroes, equal-card feature grids), three parametric dials (DESIGN_VARIANCE / MOTION_INTENSITY / VISUAL_DENSITY), and four mutually-exclusive aesthetic archetypes (minimalist, brutalist, soft-editorial, GPT-strict).

What's included

• 8 skills (base + 4 archetype overlays + redesign + design-context-generator + always-on output-discipline)
• 2 specialist agents (design-critic for audits, component-designer for implementation)
• 3 recipes (image-to-code, redesign-audit, design-system-bootstrap)
• 1 always-on behavior (output-discipline) — domain-agnostic, useful beyond frontend work

Attribution

All substantive design rules (the parametric dials, named bans, archetype palettes, the Bento 2.0 paradigm, the Doppelrand pattern, the image-to-code workflow, the research-backed output discipline) are Leonxlnx's original work. This adaptation reformats those skills into Amplifier bundle/skill/behavior/recipe conventions without modifying the substantive design guidance. Users of this bundle are asked to star the upstream repo and credit Leonxlnx — see LICENSE and README.md in the adapted bundle for the full attribution.

Quality

• v0.3.0 tagged and released (3 expert review passes, 2 critical correctness bug fixes, full context-sink extraction, GitHub Actions bundle validation)
• All YAML parses, all @taste: cross-references resolve, all skill/agent frontmatters valid
• Pure-Markdown content bundle — no Python module dependencies

Checklist for reviewer

• Bundle is publicly accessible
• LICENSE present and matches upstream (MIT)
• Attribution to upstream prominent in README
• Bundle YAML parses cleanly
• No Python modules running arbitrary code at load time
• Versioned (v0.3.0 tagged)
