Replace the bare #[tokio::main] with an explicit runtime::Builder so both
pools are sized, logged at startup, and operator-tunable.
#[tokio::main] hides two defaults that misbehave under container limits:
- worker_threads = available_parallelism(), which honours CPU affinity
(sched_getaffinity: cpuset, taskset) but IGNORES the CFS bandwidth quota
(docker --cpus, cgroup v2 cpu.max, v1 cpu.cfs_quota_us). On a 2-core-quota
container on a 64-core host it spawns 64 workers time-slicing 2 cores.
- max_blocking_threads = 512, a multi-GB RSS blast radius for this heavy
spawn_blocking user (thumbnails, transcode, zip, PDF/text extraction,
Argon2 ~19 MB/hash).
New common::runtime module folds the CFS quota back in: effective_parallelism()
= min(available_parallelism, cgroup quota). runtime_pool_sizes() defaults
workers to that and caps the blocking pool at max(32, 8*workers), both
overridable via OXICLOUD_WORKER_THREADS (or TOKIO_WORKER_THREADS) and
OXICLOUD_MAX_BLOCKING_THREADS. The cgroup v1/v2 parsers are pure + unit-tested.
Note: this corrects the premise that "rayon respects the quota, tokio doesn't"
— the image/rayon pools also use available_parallelism(), so they over-spawn
under a CFS quota too; effective_parallelism() is the reusable fix. Unset env
on an uncontended host reproduces the previous worker count exactly.
