release(vscode): v0.4.0 (#910)

Bump the extension to 0.4.0 to ship the accumulated @repowise-dev/ui changes
(graph, health, docs, C4) that have been bundled but unreleased since the
extension last shipped at the v0.27.0 commit. MIN_SERVER_VERSION stays at 0.26.0
(no new server contract required). Document the bundled-UI freeze trap in the
release checklist.

+## When to cut a release (don't let the bundled UI freeze)
+
+The webviews compile `@repowise-dev/ui` (`packages/ui`) into the VSIX at build
+time, so shared-component improvements reach extension users only on a rebuild.
+The extension source can go untouched for cycles while its bundled UI drifts,
+leaving users frozen on whatever `packages/ui` shipped at the last `vscode-v*`
+tag. Cut a release whenever `packages/ui` changed in a webview-consumed subpath
+since the last extension tag, even if `packages/vscode/` itself did not:
+
+```
+LAST_EXT_TAG=$(git tag --list 'vscode-v*' --sort=-v:refname | head -1)
+git log $LAST_EXT_TAG..origin/main --oneline -- packages/ui/src/
+```
+
+Webview-consumed subpaths: `graph/`, `health/`, `docs/`, `c4/`, `refactoring/`,
+`lib/format`, `ui/`, `shared`, `wiki/`. Confirm the live import set with
+`git grep -hoE 'from "@repowise-dev/ui[^"]*"' -- 'packages/vscode/webview/**'`.

 ## The one rule that has bitten us before
 
 **CI (and this checklist) must BUILD, not just type-check.** A barrel
