chore: delete stale web/ deployment files (now at repo root)

Removes: web/Dockerfile, web/docker-compose.yml, web/docker-compose.prod.yml,
web/deploy.sh, web/litestream.yml, web/router/, web/.copier-answers.yml,
web/.env.example — all superseded by root-level counterparts.

 ## [Unreleased]
 
+### Changed
+- **Monorepo copier migration**: moved all deployment files from `web/` to repo root so
+  `copier update` can manage them from the template
+  - `Dockerfile` at root: updated for monorepo layout (`web/src/` paths, `--package beanflows`)
+  - `docker-compose.yml`, `docker-compose.prod.yml`, `deploy.sh`, `litestream.yml`, `router/`
+    all moved to root
+  - `deploy.sh`: fixed sops path (`$APP_DIR/.env.prod.sops`, was `$APP_DIR/../.env.prod.sops`)
+  - `.copier-answers.yml` at root: points to local template, `_commit: v0.19.0`
+  - `.env.example` at root: updated paths for root-relative DuckDB locations
+  - `web/src/beanflows/core.py` (`Config`): added `ENABLE_CMS`, `ENABLE_DAAS`, `ENABLE_DIRECTORY`,
+    `ENABLE_LEADS`, `BUSINESS_MODEL` feature flags (mirrors copier.yml questions)
+  - `supervisor.py`: `web_code_changed()` now checks root `Dockerfile`; deploy script is `./deploy.sh`
+
