* feat(#1854): offer restore for user-added files backed up on update

Adds a restore-custom-files gsd-tools verb and wires it into update.md as a
restore_custom_files step: plan, compatibility-check against the newly
installed release, then restore only on explicit opt-in. The backup is never
deleted, a shipped path is never overwritten, and a single unwritable entry
does not abort the rest.

Also drops the jq pipe from update-context field extraction (#2589 class,
missed by that sweep) and repairs a broken code fence in docs/CLI-TOOLS.md.

* fix(#1854): reject symlinked restore destinations and backup roots

Self-review of the restore path found two write-through holes: copyFileSync
follows a symlinked destination, so a link planted at the restore target wrote
outside the config dir with every ancestor still a real directory; and statSync
on the backup root followed a link, letting the walk read arbitrary files and
present them as the user's own backup. Both now lstat.

Also marks the report's path/detail strings as untrusted data in update.md so
the rendered step cannot carry instructions into the runtime model.

* test(#1854): move the update-context jq guard into the #2589 sweep

update.md joins the AUDITED list rather than carrying a duplicate assertion in
the backup-restore suite, and the guard gains a negative-proof companion so
'no jq pipe' cannot pass by the fields simply no longer being read.

* fix(#1854): validate manifest files map shape before trusting it

Security review flagged that Object.keys on a non-plain-object files field
yields numeric-index keys matching nothing, so the managed-path check dies
silently while manifest_found still reports true. Shape, not just type
(ADR-227): an array or scalar files map is now an unusable manifest.

* fix(#1854): size the restore prompt by eligible_count

Spec review found the prompt was driven by entries.length, so a backup holding
only blocked entries asked "Restore 1 file(s)?" when accepting would restore
zero. The question now reads eligible_count, and an all-blocked backup reports
its reasons instead of offering a choice that cannot be honored. The decline
path names the resolved backup_dir rather than the bare directory name.

* test(#1854): use t.skip on hosts without symlink support

A bare return in a node:test body registers as a PASS, so the four symlink
guards silently reported green on unprivileged Windows instead of skipping.
Adds the dangling-link destination case the security review called out, and
moves outside-dir teardown to t.after so a failing assert cannot leak it.

* fix(#1854): unfence restore hint, regen goldens, widen install timeout

Three gate failures from the c99d612a5 run, all root-caused:

1. capability-registry (3): update.md's decline message put an instructional
   'gsd-tools ...' line in an UNTAGGED fence, and the guard treats untagged
   fences as shell blocks. Retagged both display blocks as text and switched
   the hint to the resolved 'node <config-dir>/.../gsd-tools.cjs' form users
   can actually paste.

2. golden-install-parity (19): update.md and gsd-tools.cjs ship, so every
   runtime fixture moved. Regenerated; the diff is exactly those two hashes
   per fixture, no other drift.

3. install.test.cjs (5): one real failure, four cascades. The Cursor suite's
   before hook died on 'spawnSync ETIMEDOUT' at the 60s cap while the node22
   lane passed the SAME commit in 12.7s. A full install measures 13-30s idle,
   so 60s was under 2x headroom and shrinks with every file added to the
   payload. Raised to 120s, matching the heavy case already in this file.

### GSD Update Overwrote My Local Changes
Since v1.17, the installer backs up locally modified files to `gsd-local-patches/`. Run `/gsd-update --reapply` to merge your changes back.
Which recovery you need depends on whether you *modified a GSD file* or *added your own*:
- **You edited a file GSD ships** (an agent prompt, a workflow). Since v1.17 the installer backs it up to `gsd-local-patches/`. Run `/gsd-update --reapply` to merge your changes back.
- **You added your own file inside a GSD-managed directory** (a custom skill under `skills/`, an extra file in `commands/gsd/`). The installer saves it to `gsd-user-files-backup/`, and the update offers to restore it once the new version is installed. If you declined, or the backup is left over from an older update, restore it any time:
```bash
node <config-dir>/gsd-core/bin/gsd-tools.cjs restore-custom-files --config-dir <config-dir> --apply
```
Run it without `--apply` first to see what would be restored. The backup is never deleted, and the restore skips any file that would overwrite something the new release ships.
