[2.23.0] Major update to agent-native-architecture skill (#70)
Align skill with canonical Agent-Native Architecture document:
## Core Changes
- Restructure SKILL.md with 5 named principles from canonical:
- Parity: Agent can do whatever user can do
- Granularity: Prefer atomic primitives
- Composability: Features are prompts
- Emergent Capability: Handle unanticipated requests
- Improvement Over Time: Context accumulation
- Add "The test" for each principle
- Add "Why Now" section (Claude Code origin story)
- Update terminology from "prompt-native" to "agent-native"
- Add "The Ultimate Test" to success criteria
## New Reference Files
- files-universal-interface.md: Why files, organization patterns, context.md pattern, conflict model
- from-primitives-to-domain-tools.md: When to add domain tools, graduating to code
- agent-execution-patterns.md: Completion signals, partial completion, context limits
- product-implications.md: Progressive disclosure, latent demand discovery, approval matrix
## Updated Reference Files
- mobile-patterns.md: Add iOS storage architecture (iCloud-first), "needs validation" callouts, on-device vs cloud section
- architecture-patterns.md: Update overview to reference 5 principles and cross-link new files
## Anti-Patterns
- Add missing anti-patterns: agent as router, build-then-add-agent, request/response thinking, defensive tool design, happy path in code
