feat(orchestrator): slice 13c(vii) — stable shared gateway CA

The consolidated gateway TLS-intercepts every bottle, so all agents must
trust ONE CA. Rather than host-generate + mount a CA, let the gateway's own
mitmproxy generate its CA into a persistent named volume and extract the
cert for agents — no host openssl, keeps gateway.py lean.

- DockerGateway mounts GATEWAY_CA_VOLUME at /home/mitmproxy/.mitmproxy so the
  self-generated CA survives container recreation (it must not rotate, or
  already-launched agents would stop trusting the gateway).
- ca_cert_pem(): read the CA cert (PEM) out of the running gateway
  (docker exec cat mitmproxy-ca-cert.pem) — the agent installs this into its
  trust store to accept the gateway's bumped certs.

pyright 0 errors; pylint 9.83/10; unit suite green (the 13 test_sidecar_init
/bin/sleep errors are pre-existing NixOS-local noise).

 ## Architecture
 
-On the default macOS Apple Container backend, a bottle is an agent container on a host-only internal network plus a gateway attached to both that internal network and a NAT egress network. The agent gets HTTP(S)_PROXY and CA bundle env vars pointing at the gateway's internal-network IP, so HTTP/HTTPS traffic flows through the gateway instead of direct egress. `bottle.git` / git-gate is intentionally deferred on this backend until a safe Apple Container key-delivery path exists.

-On the Firecracker backend, a bottle is an agent microVM plus a Docker gateway for egress, git-gate, and supervise. The VM reaches the gateway over a per-bottle point-to-point TAP link; a dedicated fail-closed `nftables` table (`inet bot_bottle_fc`) confines the guest to that link, so nothing leaves the box except through the gateway. The TAP pool and nft table are provisioned once (root); per-launch needs no privilege.

+It is an **idempotent singleton**: `ensure_running` returns immediately if a
+healthy control plane already answers on the port, and otherwise spawns one
+and waits for it to come up. The control-plane port is the singleton key —
+a second orchestrator can't bind it, so a stray double-start fails fast
+rather than forking a rival.
+
+Host-process (not container) on purpose: the PRD sequences the orchestrator
+as a plain-process dev-harness first (fast iteration, and it already has the
+host user's docker access to broker launches), while the data-plane
+*gateway* it manages runs as a container. Wrapping the orchestrator itself
+in a backend-native unit is a later step.

-> `CLAUDE_CODE_OAUTH_TOKEN=egress-placeholder`); the real token is held
-> in the egress sidecar and injected as the upstream `Authorization`
-> header. Rather than adding a *separate* in-container reverse proxy (as
-> proposed below), credential injection was folded into the **existing
-> pipelock/mitmproxy egress firewall**: an `EgressRoute` carries
-> `auth_scheme` + `token_ref`, the host token is forwarded into the
-> sidecar addon under an `EGRESS_TOKEN_N` slot, and the addon rewrites
-> `Authorization` on matching routes — **one MITM, not two** (this
-> resolves the Infisical-doubling concern noted later). The same
-> mechanism now covers Codex and Pi provider tokens and git-host PATs.
-> A `printenv` inside the bottle yields the placeholder, not the secret.

-  credentials, even via `printenv`." OneCLI does that one job well, is mature

-  sandboxing (containers/microVMs), no fleet/manifest layer, no named agents /

-  firewall.
-
-  **Our edge:** (1) *Isolation is the product, not a proxy.* OneCLI keeps the
-  key out of reach at the network layer, but the agent itself still runs
-  unsandboxed — a hijacked agent behind OneCLI has full run of its host and can
-  exfil captured data through any allowed host. bot-bottle runs the agent inside
-  a kernel/VM-enforced sandbox, injects credentials across that same
-  out-of-process boundary, *and* clamps egress with pipelock — defense in depth
-  vs. a single network layer. (2) *Fleet + manifest model* with named agents,
-  skills, per-agent system prompts, multi-provider and multi-backend — OneCLI
-  has no equivalent. (3) *Trust posture:* OneCLI's managed tier reintroduces a
-  third-party credential custodian, whereas bot-bottle's OSS-runtime +
-  paid-control-plane split keeps custody inside the operator's own boundary —
-  the stronger story for the security-minded self-hoster. (4) *Runs inside your
-  network boundary — local/internal reach.* Because bot-bottle executes the
-  agent on your own host (homelab, corporate LAN, a Tailnet) and egress is a
-  manifest field, giving an agent *scoped* access to **internal** resources — a
-  private Gitea, a LAN database, a Tailscale node — is just another egress-route
-  line, not a networking project (the same move an operator already makes to
-  reach their Tailscale services). OneCLI's OSS core can self-host too, but it's
-  a credential *broker* for outbound API calls, not an agent runtime, and its
-  managed tier + 50+ integrations are oriented at public SaaS — it doesn't put
-  the agent behind your firewall for you. This is a reach advantage, distinct
-  from the isolation ones above, and it's a wedge cloud-first agent products
-  (Devin, Copilot Workspace, OneCLI Cloud) structurally can't match. **Tactical
-  read:**
-  adopt OneCLI's OSS core for the credential slice if building is undesirable
-  (it's mature now); don't build atop its managed tier (competitor, not
-  dependency); re-position bot-bottle on isolation + fleet + self-hosted custody

-fixed gateway/orchestrator names (that's what it's testing), so it can't run
