Open the `wd` browser diff viewer so the USER can review changes themselves. Trigger ONLY when the user explicitly references wd or asks to look at the diff themselves — "open wd", "open a wd review", "review with wd", "let me review with wd", "let me look at the diff", "show me the diff". DEFAULT is read-only — run plain `wd` and stop. Drive the interactive `wd -c` loop ONLY when the user explicitly asks for it ("review with wd interactively", "stream my comments back", "wd -c", "drive the review"). Do NOT trigger on a bare "review my changes"/"review the diff" with no mention of wd — that means the user wants Claude to perform a code review (use the code-review skill), not the wd viewer. If the user runs `wd` themselves, do nothing. Note: invoking `/wd-review` by name (slash command) starts INTERACTIVE mode by default; the read-only default applies only to natural-language auto-triggers.
