feat: rename inquirerer to genomic and create @genomic packages

Summary

This PR renames the CLI library packages to use the @genomic scope and creates a new utilities package:

Package Renames:

• inquirerer → genomic (v3.0.0)
• create-gen-app → @genomic/scaffolds (v1.0.0)

New Package:

• @genomic/utils (v1.0.0) - CLI lifecycle utilities extracted for reuse:
  • extractFirst() - command routing utility for extracting first positional arg
  • cliExitWithError() - error handling with optional beforeExit cleanup hook
  • checkForUpdates() - npm version checking with configurable registry and caching via appstash
  • getSelfPackageJson() / getSelfVersion() / getSelfName() - package.json resolution helpers

Other Changes:

• Renamed Inquirerer class to Prompter (cleaner API: import { Prompter } from 'genomic')
• Renamed InquirererOptions to PrompterOptions for consistency
• Added "Formerly inquirerer" note to README with npm link
• Updated all internal package references in create-gen-app-test

This is a BREAKING CHANGE with no backwards compatibility as requested.

Updates since last revision

• Renamed class from Genomic → Prompter (and GenomicOptions → PrompterOptions) for a cleaner public API
• Added "Formerly inquirerer" note to genomic README
• Fixed scaffolds and create-gen-app-test packages to use Prompter class name
• Updated test snapshots to use Prompter in describe blocks
• Changed variable naming convention: use const prompter = new Prompter() (not const genomic = ...)
• Removed exports field from genomic package.json per user request

Review & Testing Checklist for Human

• Verify class/variable rename completeness: Search for any remaining Genomic, genomic (as variable name), Inquirerer, or inquirerer references that may have been missed by the sed replacement
• Review @genomic/utils implementation: The new utilities in packages/utils/src/ have no tests - verify checkForUpdates correctly uses appstash() API and getSelfPackageJson correctly imports from find-and-require-package-json
• Check hardcoded version: In packages/create-gen-app-test/src/cli.ts lines 18-19, version is hardcoded as '1.0.0' - confirm this is acceptable vs dynamic resolution
• Test package consumption: After merging, verify packages can be installed and imported correctly with new names (import { Prompter } from 'genomic')

Recommended Test Plan:

1. Run pnpm build to verify all packages compile
2. Run pnpm test to verify existing tests pass
3. Create a test project that imports genomic, @genomic/scaffolds, and @genomic/utils to verify exports work
4. Verify import { Prompter, PrompterOptions } from 'genomic' works correctly

Notes

This PR covers only the dev-utils repository. The constructive repository imports will need to be updated separately (see constructive#502).
