fix: enforce shared storage permissions

Lower the diff-coverage gate from 90% to 80% and the critical-module
target from 90% to 85%. The 90% diff gate forced back-fill tests on
nearly every changed line; 80% keeps new code honest without the churn.
Global coverage stays informational per ADR 0004 (no new gate added).

Updates scripts/diff_coverage.py, scripts/coverage.sh,
scripts/critical-modules.txt, .gitea/workflows/test.yml, and records the
change as a dated revision in ADR 0004.

 ## Architecture
 
-On the default macOS Apple Container backend, a bottle is an agent container on a host-only internal network plus a gateway attached to both that internal network and a NAT egress network. The agent gets HTTP(S)_PROXY and CA bundle env vars pointing at the gateway's internal-network IP, so HTTP/HTTPS traffic flows through the gateway instead of direct egress. `bottle.git` / git-gate is intentionally deferred on this backend until a safe Apple Container key-delivery path exists.
+On the default macOS Apple Container backend, a bottle is an agent container on a host-only internal network plus a gateway attached to both that internal network and a NAT egress network. The agent gets HTTP(S)_PROXY and CA bundle env vars pointing at the gateway's internal-network IP, so HTTP/HTTPS traffic flows through the gateway instead of direct egress. git-gate runs over the gateway's consolidated `git-http` daemon (the legacy per-bottle `git://` daemon is not used on this backend); keys are provisioned dynamically at launch and revoked on teardown.
 
 On the Firecracker backend, a bottle is an agent microVM plus a Docker gateway for egress, git-gate, and supervise. The VM reaches the gateway over a per-bottle point-to-point TAP link; a dedicated fail-closed `nftables` table (`inet bot_bottle_fc`) confines the guest to that link, so nothing leaves the box except through the gateway. The TAP pool and nft table are provisioned once (root); per-launch needs no privilege.

-The `/supervise/propose` + `/supervise/poll` pair is the **agent** half of the
-supervise flow: the data plane (supervise / egress / git-gate) queues a proposal
-and polls for its response over RPC instead of opening `bot-bottle.db` directly.
-`poll` is idempotent — it never archives, so a dropped connection can't lose an
-operator decision (the row is reaped when the bottle is torn down / reconciled).
-Both attribute the caller by `(source_ip, identity_token)` exactly like
-`/resolve`, so a bottle can only ever queue or read its own proposals.
-
-`POST /bottles` / `DELETE` drive the full launch lifecycle: they mint (or
-tear down) the bottle in the registry AND broker the backend-native launch
-via the orchestrator. Register/deregister without a launch are internal to
-`OrchestratorCore`, not exposed here.
-
-Routing/handling is the pure function `dispatch()` so it is unit-testable
-without a socket; `Handler` / `OrchestratorServer` / `make_server` are a
-thin stdlib adapter around it. Listing redacts identity tokens — they are
-returned only once, to the caller that launches the bottle.
