Four mechanical simplifications to amy with no change to the public
CLI/JSON contract:
1. Drop the Commands.kt pass-through layer. Main.kt now calls each
command object directly; the file is repurposed into Router.kt,
holding a single shared `route(name, tail, usage, routes)` helper.
2. Replace the `Context.open(dataDir)` + `try { } finally { ctx.close() }`
boilerplate (~46 sites) with `Context.open(dataDir).use { ctx -> }`
now that Context is AutoCloseable.
3. Remove the reflection-based `storeIsInitialized()` in Context; track
the lazy event store via `Lazy.isInitialized()` instead.
4. Route every `*Commands.dispatch` through the `route` helper, dropping
the repeated empty-check + unknown-verb `when` boilerplate.
Net -282 lines. Docs (cli/DEVELOPMENT.md, amy-expert skill + template)
updated to the new wiring.
