docs: add role and git.fetch to egress route fields table

Both fields were missing from the reference table added in the preceding
commit — `role` is visible in examples/bottles/claude.md and `git.fetch`
is documented in PRD 0052 but neither appeared in the README table.

+- **Per-bottle egress allowlist** — TLS-bumped HTTP/HTTPS chokepoint with a per-manifest host allowlist; per-route path/method/header `matches` filtering; outbound DLP scanning for known tokens and secrets, inbound DLP scanning for prompt-injection attempts; DoH and arbitrary hosts blocked by default.
 - **Tokens the agent never sees** — host secrets live in a sidecar; the agent dials `http://sidecar:9099/<path>` and the proxy strips inbound `Authorization` and injects the real token before forwarding. `printenv` in the agent shows proxy URLs only.
 - **Gitleaks-scanned push (git-gate)** — `bottle.git` remotes route through a per-bottle `git daemon` that gitleaks-scans incoming refs pre-receive and forwards clean refs upstream over SSH. The agent never holds the upstream credential.
 - **Manifest-scoped skills + secrets** — each bottle declares its skills, env, git identity, remotes, and egress routes; unknown keys die at load.

+**Egress route fields:**
+
+| Field | Required | Description |
+|---|---|---|
+| `host` | yes | Hostname to allowlist. One entry per host. |
+| `role` | no | Provider-specific role string (e.g. `claude_code_oauth`). Wires built-in auth flows; set by provider templates, not manually. |
+| `auth.scheme` | when `auth` present | `Bearer` or `token`. Injected by the proxy; the agent never sees the value. |
+| `auth.token_ref` | when `auth` present | Env-var name holding the secret on the host. |
+| `matches` | no | Array of `{paths, methods, headers}` filters. A request must match at least one entry (if any are given) to be forwarded. |
+| `matches[].paths` | no | Array of `{type, value}`. `type` is `prefix` (default), `exact`, or `regex`. |
+| `matches[].methods` | no | Array of HTTP method strings, e.g. `[GET, POST]`. |
+| `matches[].headers` | no | Array of `{name, value, type}`. `type` is `exact` (default) or `regex`. |
+| `dlp` | no | Per-route DLP overrides. Omit to use defaults (all detectors on). |
+| `dlp.outbound_detectors` | no | `false` disables outbound scanning; list restricts to named detectors (`token_patterns`, `known_secrets`). |
+| `dlp.inbound_detectors` | no | `false` disables inbound scanning; list restricts to named detectors (`naive_injection_detection`). |
+| `git.fetch` | no | `true` permits smart HTTP clone/fetch (`git-upload-pack`) for this host. Push (`git-receive-pack`) remains blocked. |

 More examples in `examples/`. Full design lives under `docs/prds/`; the trust-boundary rationale is in `docs/prds/0011-per-file-md-manifest.md`.
