release v0.9.7: kernel_range drift fix + CI Node 24 readiness

Tags the maintenance work landed since v0.9.6. The fragnesia drift fix (35c33df) and checkout v4->v6 bump (6c148e2) are already on main; this commit adds the remaining CI Node-24 bumps + version strings.

release.yml: upload-artifact v4->v7, download-artifact v4->v8, softprops/action-gh-release v2->v3 (last of the Node-20-era actions; GitHub forces node24 on 2026-06-16). Reviewed each changelog — our default-zip/unique-name upload + full-set download is unaffected by the major-version breaking changes (opt-in direct uploads, download-by-ID path).

Version bumped to 0.9.7 (skeletonkey.c, README, docs/index.html) + v0.9.7 RELEASE_NOTES entry. Tagging this commit fires release.yml — the end-to-end test of the new artifact actions, incl. the Alpine/musl static job under node24.

+## SKELETONKEY v0.9.7 — kernel_range drift fix + CI Node 24 readiness
+
+Two maintenance fixes, no new modules.
+
+**`fragnesia` kernel_range drift.** Debian backported CVE-2026-46300 to
+the 5.10 oldstable branch (bullseye 5.10.257), a branch the module's
+`kernel_patched_from` table didn't model — on a patched bullseye host
+`detect()` would have false-positived VULNERABLE. Added the `{5,10,257}`
+entry; the weekly `refresh-kernel-ranges.py` drift gate is green again.
+(The other flagged modules are INFO-only "more permissive" thresholds
+the check tolerates by design.)
+
+**CI Node 24 readiness.** GitHub forces the Node 24 Actions runtime on
+2026-06-16 and removes Node 20. Bumped every workflow action off its
+Node-20 line:
+
+- `actions/checkout` v4 → v6
+- `actions/upload-artifact` v4 → v7
+- `actions/download-artifact` v4 → v8
+- `softprops/action-gh-release` v2 → v3
+
+Each was reviewed against its changelog: the artifact flow uploads
+default-zipped, uniquely-named artifacts and downloads the full set, so
+none of the major-version breaking changes (opt-in direct uploads,
+download-by-ID path changes) apply. This release is itself the
+end-to-end test of the new artifact actions.
