pyranota fadbd73dc6 perf(agent-workers): two-stage prefetch pipeline for agent throughput
Experimental and env-gated (defaults off — stock behavior unchanged).

Read path is made fully non-blocking on both sides so neither the worker
nor the server waits on the stage behind it:
  Postgres -> [server-side buffer] -> HTTP -> [agent-side buffer] -> worker

- batch pull/complete: N jobs per pull, N completions per flush, so the
  per-job HTTP round-trips and per-job dequeue queries are amortized
- server-side prefetch: a single background puller per job-tag-set runs
  the SKIP LOCKED dequeue ahead of demand and coalesces concurrent agents,
  moving the PG query off the request critical path
- agent-side prefetch: a background refiller keeps the local job buffer
  deep (high low-watermark + several refills in flight) so the worker
  loop pops without a network call
- empty-pull backoff fix: don't apply the idle long-sleep to a transient
  empty pull from a prefetching consumer
- AGENT_PROF: per-phase profiler + auto-rendered per-job time-budget SVG

Single agent goes from ~2.5k to ~125k+ j/s. Multi-agent collapse is
reproduced but its root cause is still open (not established to be PG).

Windmill Backend

This folder holds all backend components, the src/ folder only contains files used to build the "root" binary.

Components

name description
windmill-api The API server, exposing functionality to other components and the frontend
windmill-audit Contains audit functionality, allowing different components to record important actions
windmill-common Common code shared by all crates
windmill-queue Contains job & flow queuing functionality, commonly written to by the API server and read from by workers
windmill-worker The worker. Used to process and execute flows & jobs.
parsers Contains code to parse signatures in different langauges.
