v0.1.3 — CLI install command and cleaning up language

Outcome: v0.1.3 — This update enables a npx command for easy installation of factory-kit via CLI. It also takes a pass at updating some agents through the factory-voice style guidelines.

Why: In open-sourcing this kit, I want to make it easy for anyone to quickly install. Right now, there is a simple git checkout and ./install-sh command, but a more common paradigm is npx commands from terminal. Thus, we have enabled `npx nonlinear-labs/factory-kit'. From a write-up perspective, skills are now structured Principle → Why → Recipe → Failure mode.

Changes:

feat:

• npx-installable CLI with symlink installer (bin/factory-kit.js); published as @nonlinear-labs/factory-kit (2c13db6)
• factory-ci and factory-testing skills — CI conventions and testing guidelines (6b3837d)

refactor:

• Skills inverted to principle-first structure with co-located recipes (66fb471)

docs / voice pass:

• Hedging removed across factory-api, factory-auth, factory-frontend, factory-forms, factory-observability ("for free" eliminated; "clever" → "auto-discovery"; passive softeners rewritten as active calls)
• /entry — section header renamed from "Constraints baked in" to "Encoded constraints" (changes how Claude phrases plan summaries)
• /standup — removed "Be opinionated" from the output spec (the rule is already named in the Style section)

other:

• Release strategy — 4th gate added (9902a65)
• LICENSE update (c2ff7a8)
