feat(egress): iron-proxy credential-injection firewall for sandboxes
Adds a TLS-intercepting egress proxy for remote terminal sandboxes (Docker
v1; Modal/SSH to follow).  When enabled, the sandbox holds opaque proxy
tokens; iron-proxy swaps them for real provider API keys at the egress
boundary.  Compromising the sandbox leaks tokens that only work from behind
the proxy.

Wraps ironsh/iron-proxy (Apache-2.0, Go binary).  Same lazy-install pattern
as the recently merged Bitwarden Secrets Manager integration — pinned
version, SHA-256 verified download into ~/.hermes/bin/iron-proxy, no apt
or sudo required.

Disabled by default.  Run `hermes egress setup` to mint tokens and
`hermes egress start` to launch.  The Docker backend then automatically
mounts the CA, sets HTTPS_PROXY + CA-bundle env vars, and adds the
host-gateway hostmap.

New surfaces:
  hermes egress install   — download the pinned iron-proxy binary
  hermes egress setup     — interactive wizard (supports --from-bitwarden)
  hermes egress start     — spawn the managed proxy daemon
  hermes egress stop      — SIGTERM (+SIGKILL after 5s grace)
  hermes egress status    — binary + config + pid + listening + mappings
  hermes egress disable   — flip proxy.enabled = false
  hermes egress config    — print the path to the generated proxy.yaml

Optional Bitwarden integration: `--from-bitwarden` sources the real
upstream credentials from a BSM project at proxy startup, so rotating a
key in the Bitwarden web app propagates to sandboxes on the next proxy
start without touching .env.

Hermes-side scope (v1):
  agent/proxy_sources/iron_proxy.py   — install + CA + config + lifecycle
  hermes_cli/proxy_cli.py             — `hermes egress` subcommand tree
  hermes_cli/config.py                — "proxy:" section in DEFAULT_CONFIG
  hermes_cli/main.py                  — argparse wiring (uses 'egress'
                                         because 'proxy' is the existing
                                         inbound OAuth reverse proxy)
  tools/environments/docker.py        — CA mount, HTTPS_PROXY, CA-bundle
                                         env vars, --add-host wiring

Hermetic tests cover the full lifecycle: token mint, mapping discovery,
config + mappings I/O, install pipeline (HTTP + tar + checksum all mocked),
subprocess lifecycle (Popen mocked), Docker backend arg builder.

A live E2E test (gated on HERMES_RUN_E2E=1) downloads the real iron-proxy
binary, spawns it, routes a curl request through it against a local fake
upstream, and verifies the Authorization header was swapped from the proxy
token to the real secret value (and the proxy token did NOT leak through
to upstream).

Failures (binary missing, port collision, bad token) never block agent
startup — they emit a warning and continue.  The Docker backend refuses to
start a sandbox when proxy.enabled=true but the daemon is dead, unless
proxy.enforce_on_docker is explicitly set to false.
