AOT: Deploy bundle (binary + public assets + phpc.json manifest)

[PurHur]

Problem

AOT produces a single binary (#59, #106). Web deploys need public/style.css, public/index.php entry, and env config. No packaging story.

Goal

phpc deploy or bin/compile.php --bundle dist/ creates:

dist/
  bin/app          # AOT binary
  public/          # copied assets from manifest
  phpc.json
  README.deploy

Implementation plan

1. Extend DevEx: phpc.json project manifest (entry, includes, public assets) #106 manifest: public, assets, entry.
2. Copy non-PHP assets; AOT compile entry; optional CGI wrapper script (Web: CGI/1.1 request driver (stdin/stdout, env, Status line) #50).
3. Tar/zip output; document running behind nginx + FastCGI (Language: Generators (yield and yield from) #167).

Acceptance criteria

• Bundle runs 001-SimpleWeb equivalent with Web: Runtime-populated superglobals for JIT and AOT (per-request $_GET/$_POST) #49 runtime GET
• Single command from repo root
