fix(guard): drop the wildcard-mount entry #4112 deleted — the guard fails on main

`scripts/check-wildcard-fallthrough.mjs` declared the hono adapter's
`${prefix}/storage/*` mount, which no longer exists:

    ✗ wildcard fall-through guard (#4116)
      packages/adapters/hono/src/index.ts:all `${prefix}/storage/*`
        DECLARED but not found by the scan. Moved, renamed or deleted? Update MOUNTS.

#4112 removed that mount outright — the adapter now carries a "deliberately NOT
mounted (#4087)" note in its place — because the wildcard claimed the whole
`/storage` subtree and answered its own 404 for every path `service-storage`
registers under it. That is the #4088 failure actually happening, so removal was
the fix rather than a ratchet.

#4112 and #4122 (which added this scan) were each green on their own base and
landed in that order, leaving the entry declaring a deleted mount. Reproduced on
pristine origin/main, so it is not specific to any branch — and since the guard
runs on every PR, it blocks all of them:

    git worktree add /tmp/main-check origin/main
    cd /tmp/main-check && node scripts/check-wildcard-fallthrough.mjs   # 1 problem(s)

Removes the stale entry, which is what the guard's own message asks for. The
sibling `${prefix}/auth/*` entry stays: that mount is still there
(packages/adapters/hono/src/index.ts:279), so its ratchet is still live. The
comment above them said "Both are the #4088 shape" and is now singular, with the
storage mount's removal recorded so the next reader does not have to reconstruct
why one of a documented pair disappeared.

Verified: `pnpm check:wildcard-fallthrough` self-test 15 cases, then
6 yielding / 1 ratcheted / 5 exempt across 12 namespace-claiming mounts. The two
steps that follow it in the same CI job and never got to run — check:release-notes,
check:node-version — pass too.
