Summary

@cancjs/server-fastify now finishes its shutdown inside fastify's own app.close(). A plain await app.close() lets in-flight requests finish with Connection: close and cancels the ones still running at cancelAfter, instead of resetting them or waiting on idle kept-alive connections. createShutdown(app, options) stores the options that close uses, and its shutdown() runs app.close(). Fastify cuts the close off at pluginTimeout (10 s by default), so inside fastify's close the windows are lowered to end just under it and app.log.warn reports that once; an Infinity window is lowered too, and pluginTimeout: 0 keeps it.

The server adapters are now tested against their oldest and newest supported framework versions. A framework parity spec runs the same cancel, deadline and shutdown cases through express, fastify, hono, koa and node, and a CI job server-framework-matrix runs the server suites at the floor versions and at the latest.

@cancjs/server-hono raises its peer floors to hono >=4.8.0 and @hono/node-server >=1.9.0, the oldest releases it is tested against. It stops @hono/node-server 2 from logging ERR_HTTP_HEADERS_SENT for a response cut after its head was sent, and cancelErrorHandler() logs an error the request does not own the way Hono does, with the bare error passed to console.error.

Testing

• npm run build, npm run surface:check, npm run surface:removals, npm run check:brand-keys and npm pack --dry-run for the five server packages pass on a fresh build.
• Server suites at the framework floor: parity 32, express 85, fastify 100, hono 90, koa 82, node 324 tests pass; fastify also passes on 5.10.0.
• CI passes on the head, including server-framework-matrix at the floor and at the latest.

Breaking changes

• @cancjs/server-fastify: a request that arrives on a kept-alive connection during the shutdown is answered by fastify, with 503 unless return503OnClosing is false, instead of being served. Set return503OnClosing: false to keep serving such requests.
• @cancjs/server-hono: peers hono 4.0 to 4.7 and @hono/node-server 1.0 to 1.8 are no longer supported; those users get a peer conflict and must upgrade.
