Add devcontainer-bridge (dbr) for dynamic port forwarding (#13)

* Add devcontainer-bridge (dbr) for VS Code-independent port forwarding

forwardPorts in devcontainer.json is a no-op outside VS Code. dbr provides
dynamic port auto-discovery via /proc/net/tcp polling and forwards to the
host via reverse TCP connections. Container daemon is inert without the
host daemon, so VS Code users are unaffected.

* Fix 3 CodeRabbit issues + stale doc reference

- CHANGELOG: add #### Features sub-heading, rewrite bullet as user-facing
- CLAUDE.md: forwardPorts is static, not dynamic discovery
- CLAUDE.md: fix Claude Code version ref (:1 → :1.0.5)
- devcontainer.json: pin dbr to 0.2.0 instead of :latest

+- **devcontainer-bridge (dbr)** — Ports opened inside the container are now automatically discovered and forwarded to the host, even outside VS Code. Requires `dbr host-daemon` running on the host. See [devcontainer-bridge](https://github.com/bradleybeddoes/devcontainer-bridge)

 ## Features
 
 Custom features in `./features/` follow the [devcontainer feature spec](https://containers.dev/implementors/features/). Every local feature supports `"version": "none"` to skip installation. Claude Code is installed as a native binary via `./features/claude-code-native` (uses Anthropic's official installer at `https://claude.ai/install.sh`).
+
+## Port Forwarding
+
+Two mechanisms handle port access:
+
+| Mechanism | When Active | Dynamic Discovery |
+|-----------|-------------|-------------------|
+| `forwardPorts` (devcontainer.json) | VS Code / Codespaces only | No (static list; VS Code auto-detects separately) |
+| devcontainer-bridge (`dbr`) | Any terminal client | Yes (polls `/proc/net/tcp`) |
+
+`forwardPorts` is a no-op outside VS Code — the `devcontainer` CLI ignores it. `dbr` provides VS Code-independent dynamic port discovery via a reverse connection model (container→host). The container daemon auto-starts and is inert without the host daemon (`dbr host-daemon`). Both mechanisms coexist. See [devcontainer-bridge](https://github.com/bradleybeddoes/devcontainer-bridge).
