fix(cli): inject version from package.json, fix docker hint, add --port to dev

- version.ts: replace hardcoded "0.1.0" with __CLI_VERSION__ injected by
  tsup at build time from package.json — fixes version mismatch where
  `hyperframes --version` reported 0.1.0 while package was 0.1.4
- tsup.config.ts: add define.__CLI_VERSION__ using package.json version
- render.ts: renderDocker error handler showed "Try --docker" even when
  already using --docker — changed to "Check Docker is running: docker info"
- dev.ts: add missing --port arg to embedded mode; findAvailablePort now
  starts from the user-supplied port instead of hardcoded 3002
