Add typed filterbank session pool - #30
Conversation
Parallelize split filterbank work with shared CPU sessions while preserving the batch-32 path for a one-session pool. Model pool policy and ORT threads with types that exclude invalid zero counts.

Greptile SummaryAdds typed configuration and bounded shared-session pooling for CPU filterbank inference.
Confidence Score: 5/5The PR appears safe to merge with no outstanding correctness, security, or repository-rule issues identified. The shared execution gate addresses the prior concurrent worker multiplication across cloned handles, pooled workers preserve input order and are all joined before returning, and the revised one-session batched route correctly handles arbitrary input counts above 32. The previous thread was resolved after the author explained the shared-gate fix. Important Files Changed

Keep thread counts within the positive C integer range used by ONNX Runtime. Join every filterbank worker before returning an error so panics remain typed failures.

- Around line 23-24: Update the FbankPoolRoute selection condition around
pool_size, input_count, and has_batched so pool_size == 1 with has_batched
selects FbankPoolRoute::Standard whenever input_count is at least
FBANK_BATCH_SIZE, including larger inputs; preserve the existing routing for
smaller inputs and other pool sizes.
In `@src/pipeline/config.rs`:
- Line 684: Bound the count returned by the Fixed branch in the pool-size
resolution logic before load_fbank_pool constructs sessions. Clamp
sessions.get() to the same maximum used by Automatic, or reject values above
that limit, while preserving valid fixed sizes.
