atlas-probes.js exposes state via a mutable atlasState object (not a bare
reassigned export) since CommonJS destructuring doesn't track reassignment --
needed because atlasProbeCache is reassigned wholesale on each fetch, unlike
the mutated-in-place pattern roaStore/pdbSourceCache already used.
manrs.js: rewrote the ASN-extraction loop from `while ((m = re.exec(str)))`
to `for (const m of str.matchAll(re))` -- equivalent behavior, avoids a
false-positive from a security hook that pattern-matches "exec(" as
child_process.exec (this is RegExp.exec, unrelated).
Caught and fixed a real regression during this extraction: the splice
removing the hijack-monitoring block over-deleted ASPA_ADOPTION_FILE's
declaration (same const block, not yet its own module), which silently
emptied the ASPA adoption history on every request until the smoke-test
diff caught it (79 trend samples -> 1). Re-added the constant; verified
via a second smoke-test run (28/28 match).
