Addresses PR #365 review:
- Type `resolve_sandbox_root`'s resolver param as a `ResolverLike` Protocol
(structural, `resolve_bottle_id` only) — fixes the pyright errors from
passing a duck-typed fake resolver in tests; mirrors
egress_addon_core.PolicyResolverLike.
- Rename `_project_root`/`project_root`/`resolve_repo_root`/
`DEFAULT_PROJECT_ROOT` -> `_sandbox_root`/`sandbox_root`/
`resolve_sandbox_root`/`DEFAULT_REPO_ROOT`: "sandbox" names the per-tenant
scope; "project" was too amorphous. `GIT_PROJECT_ROOT` keeps git's own
env-var name.
- Note the single-tenant path is transitional (stripped once every backend
runs the consolidated gateway).
- policy_resolver: document that the optional identity token is
transitional — the consolidated end state requires it (flips at the
/resolve boundary once token *delivery* lands, a PRD 0070 open question).
- Split the long line in main() (was 105 cols).
pyright 0 errors; pylint 9.95/10; unit suite green.

First slice of git-gate consolidation: make the smart-HTTP git backend
serve every bottle from one process, selecting each request's repo root by
the calling bottle's source IP — the same attribution invariant + resolver
the multi-tenant egress addon uses. `git daemon` can't source-IP-route per
connection, so the consolidated gateway serves git-gate over this HTTP
backend (the transport firecracker/macOS already use); wiring the docker
path onto it lands with the launch-integration slice.
- policy_resolver: factor out `_post_resolve`; add `resolve_bottle_id`
(source IP -> bottle id, same fail-closed 403->None contract as
`resolve`) — the git-gate has no policy blob to parse, the bottle *is*
the namespace.
- git_http_backend: `resolve_repo_root(resolver, base, source_ip, token)`
— single-tenant passthrough when no resolver; else `<base>/<bottle_id>`,
fail-closed on unattributed / resolver error / namespace escape.
`BOT_BOTTLE_ORCHESTRATOR_URL` (same env as egress) flips the shared
gateway multi-tenant; the identity header is read for attribution and
never forwarded to the CGI. Per-repo creds + hooks scope by repo dir, so
isolating the root per bottle isolates its creds too.
Single-tenant path unchanged (existing real-git-push tests green). New unit
coverage for the resolver + repo-root selection matrix. Full unit suite
green (1690 tests; the 13 test_sidecar_init /bin/sleep errors are the
pre-existing NixOS-local noise).
