fix(nvd): support full CVE rebuild without arg overflow (#204)

* fix(nvd): add hermes query specs to feed polling

* fix(nvd): derive platform fallback from matched targets

* fix(nvd): avoid arg overflow on full cve rescan

* fix(feed): add other platform filter for nonstandard slugs

* refactor(feed): centralize advisory platform badge mapping

* fix(feed): share platform normalization and fix tab callback typing

* refactor(feed): simplify platform descriptor fallback
