fix(quickstart): make README cp-paste flow bugless end-to-end (#1871)
Reproducing the README's quickstart on a clean clone surfaced seven
independent bugs between `git clone` and seeing the Canvas in a browser.
Each fix is minimal and local-dev-only — the SaaS/EC2 provisioner path
(issue #1822) is untouched.

Bugs fixed:

1. `infra/scripts/setup.sh` applied migrations via raw psql, bypassing
   the platform's `schema_migrations` tracker. The platform then re-ran
   every migration on first boot and crashed on non-idempotent ALTER
   TABLE statements (e.g. `036_org_api_tokens_org_id.up.sql`). Dropped
   the migration block — `workspace-server/internal/db/postgres.go:53`
   already tracks and skips applied files.

2. `.env.example` shipped `DATABASE_URL=postgres://USER:PASS@postgres:...`
   with literal `USER:PASS` placeholders and the Docker-internal hostname
   `postgres`. A `cp .env.example .env` followed by `go run ./cmd/server`
   on the host failed with `dial tcp: lookup postgres: no such host`.
   Replaced with working `dev:dev@localhost:5432` defaults that match
   `docker-compose.infra.yml`.

3. `docker-compose.infra.yml` and `docker-compose.yml` set
   `CLICKHOUSE_URL: clickhouse://...:9000/...`. Langfuse v2 rejects
   anything other than `http://` or `https://`, so the container
   crash-looped and returned HTTP 500. Switched to
   `http://...:8123` (HTTP interface) and added `CLICKHOUSE_MIGRATION_URL`
   for the migration-time native-protocol connection. Also removed
   `LANGFUSE_AUTO_CLICKHOUSE_MIGRATION_DISABLED` so migrations actually
   run.

4. `canvas/package.json` dev script crashed with `EADDRINUSE :::8080`
   when `.env` was sourced before `npm run dev` — Next.js reads `PORT`
   from env and the platform owns 8080. Pinned `dev` to
   `-p 3000` so sourced env can't hijack it. `start` left as-is because
   production `node server.js` (Dockerfile CMD) must respect `PORT`
   from the orchestrator.

5. README/CONTRIBUTING told users to clone `Molecule-AI/molecule-monorepo`
   — that repo 404s; the actual name is `molecule-core`. The Railway
   and Render deploy buttons had the same broken URL. Replaced in both
   English and Chinese READMEs and in CONTRIBUTING. Internal identifiers
   (Go module path, Docker network `molecule-monorepo-net`, Python helper
   `molecule-monorepo-status`) deliberately left alone — renaming those
   is an invasive refactor orthogonal to this fix.

6. README quickstart was missing `cp .env.example .env`. Users who went
   straight from `git clone` to `./infra/scripts/setup.sh` got a script
   that warned about an unset `ADMIN_TOKEN` (harmless) but then couldn't
   run the platform without figuring out the env setup on their own.
   Added the step in both READMEs and CONTRIBUTING. Deliberately NOT
   generating `ADMIN_TOKEN`/`SECRETS_ENCRYPTION_KEY` here — the e2e-api
   suite (`tests/e2e/test_api.sh`) assumes AdminAuth fallback mode
   (no server-side `ADMIN_TOKEN`), which is how CI runs it.

7. CI shellcheck only covered `tests/e2e/*.sh` — `infra/scripts/setup.sh`
   is in the critical path of every new-user onboarding but was never
   linted. Extended the `shellcheck` job and the `changes` filter to
   cover `infra/scripts/`. `scripts/` deliberately excluded until its
   pre-existing SC3040/SC3043 warnings are cleaned up separately.

Verification (fresh nuke-and-rebuild following the updated README):

- `docker compose -f docker-compose.infra.yml down -v` + `rm .env`
- `cp .env.example .env` → defaults work as-is
- `bash infra/scripts/setup.sh` — clean, no migration errors, all 6
  infra containers healthy
- `cd workspace-server && go run ./cmd/server` — "Applied 41 migrations
  (0 already applied)", platform on :8080/health 200
- `cd canvas && npm install && npm run dev` — Canvas on :3000/ 200
  even with `.env` sourced (PORT=8080 in env)
- `bash tests/e2e/test_api.sh` — **61 passed, 0 failed**
- `cd canvas && npx vitest run` — **900 tests passed**
- `cd canvas && npm run build` — production build clean
- `shellcheck --severity=warning infra/scripts/*.sh` — clean
- Langfuse `/api/public/health` 200 (was 500)

Scope notes:

- SaaS/EC2 parity (issue #1822): all files touched here are local-dev
  surface. Canvas container uses `node server.js` with `ENV PORT=3000`
  in `canvas/Dockerfile` — the `-p 3000` pin in `package.json` dev
  script only affects `npm run dev`, not the production CMD.
- Test coverage (issue #1821): project policy is tiered coverage floors,
  not a blanket 100% target. Files touched here are shell scripts,
  YAML, Markdown, and one package.json script — not classes covered
  by the coverage matrix.
- No overlap with open PRs — searched `setup.sh`, `quickstart`,
  `langfuse`, `clickhouse`, `migration`, `README`; nothing conflicts.
