refactor(gateway): install gitleaks by pinned+verified download, drop third-party base image (PR #354 review)
The gateway used `FROM zricethezav/gitleaks AS gitleaks-src` purely to
COPY the binary out — a supply-chain surface (a whole third-party image as
a build input, tying us to its cadence). Install gitleaks from its official
release instead, pinned by version + SHA256 and verified. python (already
in the image) does the download, so no curl/wget is added. trixie apt also
ships gitleaks but an older 8.16; the pinned download keeps the verified
8.30.1 (byte-identical to what the image provided).

Verified: gateway + infra images build, gitleaks 8.30.1 runs in both.

# Gateway data-plane image (PRD 0024 bundle shape; PRD 0070 gateway).
#
# The egress / git-gate / supervise *data plane* — one image, run by
# the consolidated per-host gateway (PRD 0070). It is NOT the
# orchestrator control plane: that is the separate, lean
# `bot-bottle-orchestrator` image (Dockerfile.orchestrator, #384), which
# ships only python + the stdlib-only `bot_bottle` package and none of
# this image's mitmproxy / git / gitleaks payload.
#
# Collapses the prior per-daemon images (egress, git-gate,
# supervise) into one. A small stdlib-Python init supervisor at
# /app/gateway_init.py spawns all daemons, forwards SIGTERM, and
# propagates per-daemon stdout/stderr to the container log with a
# `[name]` prefix. See PRD 0024 for the rationale.
#
# Layout:
#
# /usr/bin/gitleaks gitleaks binary
# /app/egress_addon.py + siblings mitmproxy addon (egress)
# /app/egress-entrypoint.sh mitmdump launcher
# /app/supervise_server.py + .py supervise MCP server

# /etc/egress/routes.yaml bind-mounted at run time

# 9100 supervise (MCP HTTP)
# Based on `python:3.12-slim` (Debian trixie) rather than the
# `mitmproxy/mitmproxy` image (Debian bookworm) so the whole stack —
# gateway here, and the firecracker infra image that builds FROM this —
# lands on trixie, whose buildah (1.39) can build agent Dockerfiles that
# use heredocs. mitmproxy is pip-installed to the same effect as the
# upstream image. (bookworm's buildah is 1.28, which can't parse
# `RUN ... <<EOF`; see the infra image + PR discussion.)
