nix-portable fell back to proot in the deployment (user namespaces are blocked
by the container's default seccomp/apparmor profile, and orca can't relax it),
and proot corrupts the nix build's file-permission syscalls — every firmware
build failed at `cp: setting permissions … No such file or directory` and fell
back to the analysis-only SBOM.
Ship a real nix instead and disable its build sandbox (`sandbox = false`): a
plain gcc/make firmware build needs no user namespace, so it runs under the
locked-down profile with no proot at all. The store ships as a compressed
bootstrap tarball (built in a throwaway `nixos/nix` stage) and is seeded onto
/nix at first start by docker/agent-entrypoint.sh, so a persistent /nix volume
survives redeploys. Seeding and the whole path are best-effort — a broken nix
just falls back to analysis-only, never breaking a scan.
No agent code change: NixBackend::detect() already prefers the system `nix`.

The PR `check` job authenticates the private tramiton-core git fetch, but the main-branch **`deploy-agent`** job builds `Dockerfile.agent` where cargo also fetches tramiton-core — inside the image build, with no credentials — so **agent image builds on main fail**.
Fix: inject the PAT as a **BuildKit secret** (never baked into an image layer).
- `Dockerfile.agent`: `RUN --mount=type=secret,id=tramiton_token …` applies the same `https`-insteadOf rewrite + `CARGO_NET_GIT_FETCH_WITH_CLI=true` before `cargo build`.
- `deploy-agent`: `DOCKER_BUILDKIT=1 docker build --secret id=tramiton_token,env=TRAMITON_FETCH_TOKEN …`, reusing the existing `TRAMITON_FETCH_TOKEN` secret.
Only the agent image depends on tramiton-core (dashboard/mcp/docs unaffected). **Self-tests on merge** — changing `Dockerfile.agent` makes `detect-changes` run `deploy-agent`.
Note: couldn't fully run the image build locally (no PAT value on hand + no `.dockerignore` so the context is large), but this mirrors the working PR-stage auth and uses standard BuildKit secret injection. Assumes the deploy runner's Docker daemon supports BuildKit (docker:27-cli → yes).

- Fetch SSH public key every time auth section opens (was only fetching
once and caching failures)
- Add mkdir for SSH key directory in Dockerfile.agent
