docs: add claude-bottle.example.json

Worked example covering two bottles (one minimal, one with all three
env-entry modes, an SSH entry, and a wider egress allowlist) and three
agents that share them. Named .example.json so manifest_resolve does
not auto-load it when running cli.py from the repo root.
