Port HTTP transport from ponylang/http to ponylang/courier (#91)

Replace the HTTP handler factory pattern (25 types: 8 requesters +
8 handler factories + 8 handlers + RequestFactory) with courier's
actor-based connection model (6 types: 4 request actors + 1 SSL
factory + 1 shared interface).

Each API call creates a short-lived actor owning an
HTTPClientConnection. Consolidation by response pattern: POST+PATCH
share JsonRequester (differ by method/expected status), DELETE+PUT
share NoContentRequester, paginated+search share LinkedJsonRequester
via a LinkedResultReceiver interface. All actors close their
connection in on_response_complete so the runtime exits promptly.

SSLContextFactory tries the system CA store for verified HTTPS; when
unavailable it falls back to unverified SSL, matching the old
HTTPClient behavior.

Breaking change: Credentials.auth changes from net.TCPConnectAuth
to lori.TCPConnectAuth. Authorization header moves from legacy
"token" format to "Bearer" format (GitHub accepts both).

Public API is otherwise preserved — all operation primitives, model
classes, OO convenience methods, and pagination work the same way.

+## Port HTTP transport from ponylang/http to ponylang/courier
+
+The HTTP transport layer has been replaced with ponylang/courier, which uses an actor-based connection model instead of the handler factory pattern. All public API operations work the same way, but `Credentials.auth` has changed type.
+
+Before:
+```pony
+use "net"
+
+let auth = TCPConnectAuth(env.root)
+let creds = Credentials(auth, token)
+```
+
+After:
+```pony
+use lori = "lori"
+
+let auth = lori.TCPConnectAuth(env.root)
+let creds = Credentials(auth, token)
+```
+
+Authorization headers now use `Bearer` format (`Authorization: Bearer <token>`) instead of the legacy `token` format. GitHub accepts both.
