End-to-end provisioning parity with the docker backend. After this
chunk a smolmachines bottle has a working trust store, git-gate
gitconfig, and supervise MCP registration — same shape as docker,
dispatched via `smolvm machine cp` / `smolvm machine exec` instead
of `docker cp` / `docker exec`.
Adds three new provision modules:
- ca.py: select egress vs pipelock CA (same logic as
docker), machine cp + update-ca-certificates,
log sha256 fingerprint.
- git.py: copy host .git when --cwd was passed; render
~/.gitconfig with insteadOf URLs. URL prefix is
`git://<bundle_ip>:9418/...` (no DNS in the
TSI-allowlisted guest) vs docker's
`git://git-gate/...`.
- supervise.py: `claude mcp add` via machine_exec; URL is
`http://<bundle_ip>:9100/`. Failure is logged but
non-fatal (matches docker).
Shared render: `render_git_gate_gitconfig` moves out of
backend/docker/provision/git.py into the platform-neutral
claude_bottle/git_gate.py (renamed to git_gate_render_gitconfig
for consistency with the existing git_gate_render_* helpers),
parameterized on a `gate_host` argument so both backends use the
same logic with different addresses.
Path/user fixups for the post-chunk-4c agent image (real
claude-bottle image, USER node, $HOME=/home/node):
- prompt.py default path moves from /root/... to
/home/node/.claude-bottle-prompt.txt; chown + chmod after
machine cp.
- skills.py default skills dir moves from /root/.claude/skills to
/home/node/.claude/skills; chown -R per skill.
