build(monorepo): split web and cli workspaces

[Vann-Dev]

Summary

• Move the Next.js dashboard/API app into apps/web and add an @agentbridge/web workspace package.
• Move the publishable CLI package from cli to packages/cli while preserving the agentbridge package name/bin.
• Keep Prisma schema/migrations at repo root and generate the client into apps/web/generated/prisma for Next build compatibility.
• Update root orchestration scripts, workspace globs, Dockerfile, ignore rules, and docs for the new layout.

Checks

• corepack pnpm install --frozen-lockfile
• DATABASE_URL='postgresql://agentbridge:agentbridge@localhost:5432/agentbridge?schema=public' corepack pnpm typecheck
• corepack pnpm lint
• DATABASE_URL='postgresql://agentbridge:agentbridge@localhost:5432/agentbridge?schema=public' AUTH_SECRET='build-placeholder-secret' corepack pnpm build:web
• corepack pnpm cli:build
• corepack pnpm cli:pack

Note: Next build emits existing warnings about the deprecated middleware file convention and jose CompressionStream/DecompressionStream in Edge Runtime, but exits successfully.
