chore: standardize .npmrc + workspace for corp network resilience

- .npmrc: use ${GITEA_NPM_HOST:-localhost}:3300 instead of hardcoded
  gitea.bytelyst.com (corp TLS proxy breaks external URL).
- pnpm-workspace.yaml: add ../learning_ai_common_plat/packages/* so
  @bytelyst/* resolve locally without registry access.
- .npmrc: enable link-workspace-packages + prefer-workspace-packages.
