steve a781e95c94 P3 follow-up: editable target dir, conditional --no-ownership, UK lint
Three small follow-ups from review:

1. Restore target is now operator-editable. Default value is the
   literal '\$HOME/rm-restore/<job-id>/' (agent expands \$HOME at
   run time using os.UserHomeDir(); also handles \${HOME} and ~/
   prefixes). Operator can replace with any absolute path.
   - ui_restore.go validates the input is either absolute or starts
     with one of the recognised prefixes; other env-var refs (\$PATH
     etc.) are deliberately rejected so operator paths can't pick up
     arbitrary agent env values.
   - host_restore.html replaces the read-only mono-text display with
     a real <input>; help text spells out that \$HOME resolves
     agent-side and <job-id> is substituted on dispatch.
   - install.sh + the systemd unit prep /root/rm-restore so the
     default works under the sandbox: ReadWritePaths gains a soft
     '-/root/rm-restore' entry (the '-' makes the bind-mount soft-fail
     if missing, but install.sh pre-creates it root-owned 0700).

2. --no-ownership flag now gated on restic version. The flag was
   added in restic 0.17 and 0.16 rejects it. Previously dropped it
   wholesale — that meant new-dir restores silently preserved
   ownership against design intent on 0.17+. Now the agent threads
   its detected restic version (sysinfo already collects it) through
   runner.Config -> restic.Env, and RunRestore appends --no-ownership
   only when AtLeastVersion(0, 17) returns true. 0.16 hosts still
   restore with original uid/gid; help text in the wizard explicitly
   notes this. The previous 'Original ownership is preserved' copy
   was wrong for new-dir mode and is corrected.

3. golangci-lint misspell locale switched US -> UK and the codebase
   swept (73 corrections, mostly behaviour/serialise/recognise/honour).
   Wire-format ErrorCode 'unauthorized' -> 'unauthorised' is a tiny
   contract change but the agent doesn't parse those codes today and
   no external API consumers exist yet. Tests passed before + after.

Tests:
- internal/restic/version_test.go covers Env.AtLeastVersion across
  edge cases (empty, exact match, patch above, minor below, non-
  numeric) and expandHome on \$HOME / \${HOME} / ~/, plus
  pass-through for absolute paths and refusal of other env vars.
- ui_restore_test updated: TargetDir now starts '\$HOME/rm-restore/'
  with the job_id substituted into the placeholder.

Live verified on the smoke env: default target restored to
/root/rm-restore/<job-id>/ as the agent's expanded \$HOME (2 files,
14 bytes); custom override '/tmp/custom-restore/<job-id>/' restored
into the agent's PrivateTmp namespace (1 file, 6 bytes); both jobs
'succeeded', exit 0.

steve 65a0134101 P3 sweep fixes: snap-row CSS, tree expand, --no-ownership drop, target path
Bug fixes from the Playwright sweep against the live smoke server:

1. Snapshot-picker layout. The .snap-row class was used in the wireframe
   but never landed in web/styles/input.css; rows rendered as vertical
   blocks instead of a 6-column grid. Added the token (mirrors host-row
   shape with restore-specific column widths).

2. Tree expansion. hx-target='closest .tree-row + .tree-children' isn't
   a valid HTMX selector — modifiers don't chain. Replaced HTMX-driven
   expansion with a small window.__rmTreeToggle helper that uses plain
   fetch + .tree-pair wrapper structure for trivial sibling lookup.
   Caches loaded state per node.

3. --no-ownership flag dropped. Restic 0.17 introduced --no-ownership;
   0.16 rejects it ('unknown flag') before doing any work. Since the
   agent runs as root in the systemd unit, restored files keep their
   original uid/gid either way and the parent dir is root-owned, so
   the 'cp without sudo' rationale doesn't hold. Drop the flag entirely.

4. Default target dir moved to /var/lib/restic-manager/restore. The
   systemd unit pins ReadWritePaths to /etc/restic-manager +
   /var/lib/restic-manager (with ProtectSystem=strict making the rest
   of /var read-only); writes to /var/restic-restore failed with
   'read-only file system'.

5. Confirm summary HTML escaping. defaultTarget JS literal evaluates
   to a string with literal angle brackets; insertion into innerHTML
   must escape them. Added an inline HTML-escape pass.

tasks.md ticked for the Restore sub-phase with a sweep summary
covering the live end-to-end test.

steve f5e3bca6a2 P3-03: restic restore + diff execution path
Wires JobRestore and JobDiff end-to-end at the agent layer (the wizard
backend that drives this lands in the next slice).

- internal/api: JobRestore + JobDiff JobKind constants. CommandRunPayload
  grows nullable Restore + Diff sub-payloads. RestorePayload carries
  snapshot_id, paths, in_place, target_dir; DiffPayload carries
  snapshot_a + snapshot_b.
- internal/restic.RunRestore wraps 'restic restore <sid> --target ...
  [--no-ownership] [--include p]...' with --json. New pumpRestoreStdout
  parses the per-line status / summary objects (drops raw status from
  log.stream — the throttled job.progress envelope covers it). New
  RestoreStatus + RestoreSummary types mirror restic's wire shape.
- internal/restic.RunDiff wraps 'restic diff --json <a> <b>'.
- internal/agent/runner: RunRestore translates RestoreStatus into
  job.progress (mapping FilesRestored → FilesDone etc) with a small
  estimateETA helper since restic doesn't provide ETA for restore.
  RunDiff is a thin streamHandler wrapper.
- cmd/agent dispatcher gains JobRestore + JobDiff cases. Both reuse
  the spawn() helper from P3-X1 so cancel just works.
- Drive-by fix: lastProgress was initialised to time.Now() so the
  very first status event was suppressed by the 1s throttle if the
  agent reported quickly. Initialise to time.Time{} (zero) so the
  first event always emits. Affects backup + restore.

Tests:
- restore_test covers restore happy path (started → progress →
  finished, kind=restore on the started envelope), in-place argv
  asserts no --no-ownership, new-dir argv asserts --no-ownership +
  --target + --include, diff produces the expected log.stream lines.

Restage block (CLAUDE.md) is deferred to the end of the restore
sub-phase so we restage once with all changes.
