Two related fixes on top of PR #29's chunk-2 cutover:
1. Universal HTTPS git-push block in the egress-proxy addon
(`is_git_push_request` in egress_proxy_addon_core, called from the
mitmproxy request hook before route matching). 403s any
`/git-receive-pack` or `info/refs?service=git-receive-pack` —
defense in depth so git-gate (PRD 0008) remains the only outbound
path for writes, gitleaks-scanned by its pre-receive. Replicates
cred-proxy's `is_git_push_request` behavior.
2. Restored agent-side role provisioner. Brings back `Role` on
EgressProxyRoute (manifest + runtime) with three roles —
`anthropic-base-url`, `npm-registry`, `tea-login`. Singleton
constraint on the first two carries over from cred-proxy.
`git-insteadof` is intentionally absent (option 1 above handles
the push-bypass concern, and the canonical-URL rewrite has no
function when egress-proxy is on HTTPS_PROXY).
The provisioner (`backend/docker/provision/egress_proxy.py`):
- `~/.npmrc` registry= the canonical upstream URL.
- `~/.config/tea/config.yml` logins[] entry per tea-login route.
- `ANTHROPIC_BASE_URL` env set in prepare.py based on the
anthropic-base-url role (was a token_ref="CLAUDE_CODE_OAUTH_TOKEN"
check in this PR's earlier draft — the role marker is cleaner
and matches the cred-proxy precedent the user wants kept).
All three dotfile values point at canonical upstream URLs; the
agent's HTTPS_PROXY=egress-proxy routes them through the proxy
automatically.
Tests: 11 new role-validation tests, 11 new provisioner-render tests,
the chunk-1 manifest fixture exercise role=anthropic-base-url. 400
tests pass (was 376).
