check:pack-policy failed on the release tip with 27 'unexpected files',
all of them under @omniroute/opencode-plugin-v2/.
#12870 added that package next to @omniroute/opencode-plugin and
@omniroute/opencode-provider - both already on
PACK_ARTIFACT_ROOT_ALLOWED_PATH_PREFIXES - and package.json's files field
ships the whole @omniroute/ tree, but the allowlist was never widened. The
v2 package has the same shape as the v1 sibling it was modeled on
(LICENSE, README, package.json, src/, tests/, tsconfig.json,
tsup.config.ts), so it gets the same prefix entry.
Reproduced on the clean tip d6f3150 (fails) and with this change (passes) -
check:pack-policy runs --policy-only, so no build is involved.
