fix(cli): auto-inject VERSION from package.json at build time

alpha.28-30 binaries all reported 'v1.0.0-alpha.27' from a hardcoded
constant in src/constants/urls.ts — my bump sed only matched
package.json's 'version' key, not the TypeScript literal.

build.ts now reads package.json version and injects it via Bun's
`define` (source-text replacement, equivalent to esbuild --define).
urls.ts reads the injected symbol with a runtime fallback for `bun
src/...` dev mode. Version drift can't recur.

+ peers + status migrated to the render.ts unified renderer.
