Gaoxy v0.8.0

Gaoxy 0.8.0

One Phoenix Endpoint can now own HTTP/1.1, HTTP/2 and optional HTTP/3 through
Gaoxy.PhoenixAdapter. Configure explicit http3: credentials and binding
beside http: and https:; one ListenerSet initializes the Endpoint once and
owns one core instance. Actual transport addresses, recovery state and
capabilities are inspectable. Native H2/H3 WebSocket CONNECT keeps exact socket
paths, LiveView, Channels and development code reload.

Gaoxy.Proxy.Gateway embeds the managed gateway without gaoxy_server.
Applications declare logical listener sets, share one route generation across
their H1/H2/H3 listeners, reload with an expected accepted revision, inspect
bounded operation receipts, and stop the complete runtime. Stable stores retain
accepted routes and immutable upstream trust through runtime-owner recovery.
Different gateways can reuse logical IDs independently. Standalone JSON v1,
environment/readiness output and file-based reload delegate to the same runtime.

Gaoxy.HTTP.ListenerSet supplies pure declarations and optional providers.
Supported deferred core activation preserves the complete planned resource and
shutdown budgets, owns late startup/rollback and replaces private Instance
startup. Optional readiness-aware Alt-Svc discovery runs before response-header
budget checks for secure H1/H2 native, Plug and proxy final responses, including
streaming. Discovery remains disabled by default.

Existing single-service builders, HTTP defaults and mixed cleartext
H1/prior-knowledge H2 remain supported. H3 requires gaoxy_http3; HTTP and Proxy
do not acquire a reverse dependency. Independent port-zero bindings remain
independent. Unsupported H3 bind/TLS capabilities still fail explicitly. Reload
changes routes, not listener bindings or certificates; complete root/VM loss
returns to the host's startup configuration.

The five Hex distributions and standalone application use coordinated 0.8.0
metadata. See Phoenix configuration,
embedded Gateway APIs,
ListenerSets, and the
acceptance record for
commands, evidence, known baseline failures and publication status. Specialist
pressure/soak qualification and deployment remain outside this release.
