Enable metadata-driven init defaults for workspace/module templates

[sdqede]

• Remove hardcoded templatePath defaults in init flows so .boilerplates.json drives resolution to default/workspace and default/module.
• Stop test defaults from forcing template paths; rely on scaffoldTemplate metadata lookup (with legacy fallback).
• Ensure init works on the restructuring branch without extra flags and snapshots reflect the new behavior.

⚠️ Coordinate Releases with pgpm-boilerplates Merge

• Publish @launchql/cli and pgpm only after pgpm-boilerplates restructuring is merged to main.
• Reason: lql init defaults to cloning main of pgpm-boilerplates; the new metadata layout (default/workspace, default/module, .boilerplates.json) must be present there to avoid init failures.
• Action: Merge pgpm-boilerplates restructuring → then publish @launchql/cli + pgpm together.

npm view @launchql/cli version

node packages/cli/dist/index.js init -h

cat ~/.lql/config/_launchql_cli.json

rm -rf /tmp/lql-test

node packages/cli/dist/index.js init \
  --cwd /tmp/lql-test \
  --from-branch restructuring \
  workspace

node packages/cli/dist/index.js init \
  --cwd /tmp/lql-test/workspace \
  --from-branch restructuring

ls ~/.pgpm/cache/repos
