chore: fix monorepo build pipeline and migrate shared to built package

- Root package.json: add workspace scripts (dev, build, test, test:cov, test:e2e)
  that delegate to actual scripts in shared/server/client workspaces
- shared: add tsup build step (CJS + ESM dual output, .d.ts); consumers now import
  from the built dist instead of raw TS source via path aliases
- server: replace tsc-alias with tsconfig-paths (tsc-alias mangled node_modules
  paths); fix MCP SDK path aliases to point to root node_modules (../node_modules)
- server/scripts/dev.mjs: delay node --watch until tsc -w signals first-pass done,
  eliminating the spurious restart on every dev startup
- client/vite.config.js + vitest.config.ts: remove @trek/shared path alias (no longer
  needed now that shared is a proper package)
- Consolidate package-lock.json at the workspace root; drop per-workspace lock files
