Aube’s adaptive runtime helpers. A global library of runtime tuned
lock free primitives that replace hard coded magic numbers across
the codebase with online observation.
Hash-map type aliases backed by foldhash. Better avalanche than
FxHash on integer-suffixed string keys (the shape aube’s dep_path
peer-context suffixes take). All inputs come from locked manifest
data so FixedState (no random seed) is fine, no DoS surface.
Deserialize npm platform fields (os, cpu, libc) from either a
string or an array of strings. Missing fields, nulls, and non-string
array entries mean “no constraint” and are dropped.
