Ruben Fiszel 8310e46b19 (windows) lean worker-only build, stop compiling the amqp trigger (#10251)
windmill-trigger-amqp does not compile on Windows: tokio-reactor-trait only
implements reactor_trait::Reactor for its Tokio type under #[cfg(unix)]. This
broke two Windows CI jobs since the amqp trigger landed (#10230): the ee_windows
worker build (via the amqp_trigger feature) and, because the crate is a default
workspace member, the backend-test-windows job (`cargo test --all` compiles
every member regardless of features).

The amqp trigger is a server-only feature never run on Windows workers, so the
fix is to stop compiling it on Windows rather than port its reactor.

Worker binary (ee_windows): replace the ce_core+ee_core bundle (every trigger +
all server-only features) with a worker-only worker_windows_core. A non-agent
worker still runs the full windmill-api on localhost for its own operations
(main.rs run_server, under `if !is_agent`) and jobs call back into it via the
wmill client, so keep every feature the worker's own runtime path or its jobs
touch, and drop the rest.

  Kept: languages, parquet, quickjs, enterprise/license, prometheus, otel,
  jemalloc, AI-agent execution (windmill-worker/mcp + windmill-store/mcp client
  and OAuth-MCP refresh, windmill-worker/bedrock for direct AWS Bedrock), OIDC
  Vault secrets (openidconnect), instance-SMTP email — critical alerts and the
  error-handler send endpoint (windmill-api/instance_smtp), OAuth refresh (oauth2
  — reload_base_url_setting populates OAUTH_CLIENTS, get_value_internal refreshes
  tokens in the worker's internal API server), inline/preview runs (run_inline —
  jobs call /jobs/run_inline/*).

  Dropped: all *_trigger/kafka/nats/sqs listeners plus static_frontend, stripe,
  embedding, zip, the MCP gateway (windmill-api/mcp), the server Bedrock proxy
  route (windmill-api/bedrock), and cloud (runtime-gated on CLOUD_HOSTED, never
  true self-hosted).

Split windmill-api's smtp feature: the send_email_with_instance_smtp endpoint
(error-handler failure emails) only needs windmill-common's rustls sender, but
the smtp feature also bundled the inbound email trigger's openssl + mail-parser +
windmill-trigger-email. Add instance_smtp = ["windmill-common/smtp"] gating just
the endpoint; smtp now includes it. The worker uses instance_smtp, avoiding
openssl (which broke the ee_windows check step) and the email-trigger crate.

backend-test-windows: the Windows binary is worker-only, so test the crates a
worker runs (windmill-worker/-common/-queue) via -p instead of `cargo test
--all`. --all compiled every workspace member regardless of features — pulling
in the amqp crate (which does not build on Windows) and linking the whole
windmill-api integration-test suite, whose combined size overran the runner disk
(LNK1180). Also unset the setup-rust-toolchain default RUSTFLAGS=-D warnings for
this job so cross-platform dead-code (cfg(unix)-only helpers unused on Windows)
does not fail the run; hygiene stays enforced on the Linux CI and the
build_windows_worker_ release build. Full-workspace coverage runs on the Linux CI.

Also drop the redundant `mkdir frontend/build` from the Windows worker workflows
and stub openapi-deref.json alongside the .yaml to avoid embedding ~2.5MB of
openapi spec the worker never serves.
