* 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.

Pass `--respect-staged` to skip the `git add` step and commit only what is already in the index within the requested pathspec. If nothing is staged within that scope, the command returns `{ committed: false, reason: 'nothing staged' }` without error. The trailing `-- <paths>` pathspec on the commit is applied under both modes, so files staged outside the `--files` scope are never included (#3061 invariant).

## Update Backup and Restore
The two halves of `/gsd:update`'s user-added-file protection. `detect-custom-files`
lists files that exist inside GSD-managed directories but are absent from
`gsd-file-manifest.json` — the update workflow copies those into
`gsd-user-files-backup/` before the clean-install wipe. `restore-custom-files`
puts them back afterwards.
```bash
# List user-added files the installer would destroy (JSON)
node gsd-tools.cjs detect-custom-files --config-dir <config-dir>
# Plan a restore — reports what would be restored, writes nothing
node gsd-tools.cjs restore-custom-files --config-dir <config-dir>
# Restore the eligible entries
node gsd-tools.cjs restore-custom-files --config-dir <config-dir> --apply
```
`restore-custom-files` emits one entry per backed-up file:
| Field | Meaning |
|---|---|
| `path` | Path relative to the config dir — where the file came from and goes back to |
| `outcome` | `eligible` (plan mode) · `restored` · `skipped_destination_managed` · `skipped_destination_exists` · `skipped_copy_failed` · `skipped_unsafe_path` |
| `warnings` | Advisory `{code, detail}` findings from the compatibility pass; never blocks a restore |
Warning codes: `destination_managed`, `destination_exists`,
`missing_referenced_path`, `missing_referenced_command`,
`frontmatter_missing_field`, `write_failed`.
The compatibility pass runs against the **newly installed** release, so it
catches a backed-up skill that `@`-references a workflow the new version
retired, invokes a `/gsd:` command that no longer exists, or is missing the
`name` / `description` frontmatter its runtime needs.
Three things the restore never does: it never deletes the backup, it never
overwrites a path the new release ships (`skipped_destination_managed`), and it
never overwrites a different file already on disk
(`skipped_destination_exists`). Symlinked backup entries are skipped outright
rather than followed (`skipped_unsafe_path`). A single unwritable entry is
reported and the remaining entries still restore.
