Normalize both the candidate and terminal.cwd before the remote-POSIX
containment check so `{cwd}/../other/...` lexical escapes are rejected, and
restore the blocked-system-root gate BELOW the home-directory allow-list in
both resolve_trusted_workspace() and validate_workspace_to_add() so valid
systemd-homed paths under /var/home/... stay allowed. Also normalize POSIX
shapes at the source (_as_posix_path) so every downstream block probe is
shape-consistent (/etc/../home/user -> /home/user).

## Test results
**2729 passed, 2 skipped** (2 macOS-only tests correctly skipped on Linux). Browser QA: **21/21**.
## Key fix notes
**#1186:** `_workspace_blocked_roots()` now returns both literal and `Path.resolve()` forms of each blocked root. macOS symlinks (`/etc → /private/etc`) previously let a resolved candidate slip past the literal check. New `_is_blocked_system_path()` helper with `/var/folders` and `/var/tmp` carve-outs for pytest temp dirs.
**#1187:** Regression from #1182 — `syncWorkspacePanelState()` force-closed on any no-session state. Now only closes in `'preview'` mode. Both boot paths restore localStorage panel pref before sync.
**#1190:** Fenced code blocks are now stashed as `\x00P<n>\x00` tokens through ALL markdown passes (list/heading/table regexes), restored at the very end. Previously, diff hunks and markdown headings inside code blocks triggered those regexes, injecting `<ul>/<li>/<h>` tags that broke `</pre>` closure.
