zsh: verify opc/opd against the vault and explain failures

op item edit can exit non-zero with "(404) Not Found" after an edit it
did save (seen with op 2.34.1 and 2.39.0 on an existing item), which
made opc report failure and skip the ops refresh. opc now reads the
field back and opd re-checks the item's labels, then prints either the
op:// reference it changed or what failed, op's message without its
timestamp prefix, and where to look next.

+# vscode/install.sh — install Visual Studio Code into ~/.local/opt/vscode.
+#
+# WHY: VS Code is the one GUI app this repo installs, and the obvious way to get
+# it — Microsoft's rpm/deb repo — needs root, writes outside $HOME, and is wiped
+# by a Kasm redeploy, so the editor quietly disappears on every rebuild. The box
+# this was written for had exactly that half-state: /etc/yum.repos.d/vscode.repo
+# present, `code` never installed, and nothing in this repo recording that VS
+# Code was meant to be there at all. Upstream's portable tarball is the same
+# build with none of that: everything lands under $HOME, no sudo, and it
+# survives a redeploy. The only thing given up is dnf/apt-driven updates, which
+# is what the pinned VSCODE_VERSION below replaces.
+#
+# It is not in bin/install.sh because that script installs single self-contained
+# binaries; VS Code is an Electron tree of thousands of files plus a menu entry
+# and an icon. It follows node/ and ansible/ instead: unpack under ~/.local/opt
+# and symlink the CLI into ~/.local/bin.
+#
+# The Chromium sandbox still works from a userland install: the bundled
+# chrome-sandbox helper is not setuid here, so Electron falls back to the
+# unprivileged user-namespace sandbox. That needs user namespaces enabled
+# (user.max_user_namespaces > 0, the default on every distro this repo targets).
+# Verified by launching without --no-sandbox. Nothing is given up for dropping
+# root; if a host ever has userns disabled, VS Code says so on startup.

+# and GitHub auth tokens, extension credentials) end up obfuscated on disk
+# rather than sealed behind a wallet password. To move to the wallet later,
+# install kwallet-pam so it unlocks at login, then change the value to
+# "kwallet5" and restart VS Code.
