fix(cli): omit --workspace when subpackage has its own package-lock.json (#42973) (#43986)
* fix(cli): omit --workspace when subpackage has its own package-lock.json

When ui-tui/ (or web/) contains its own package-lock.json, _workspace_root()
returns the subpackage directory itself.  Passing --workspace ui-tui in that
case fails because npm cannot find a workspace named 'ui-tui' inside ui-tui/.

Fix: skip the --workspace flag when npm_cwd equals the target directory,
running a plain 'npm install' from the standalone project root instead.

Applies the same fix to both _make_tui_argv (TUI) and _build_web_ui (web).

Fixes #42973

* test(cli): fix web workspace-scope fixture + cover own-lockfile fallback (#42973)

The web half of the #42977 fix broke test_npm_install_uses_workspace_web_scope,
which built its fixture with no lockfile anywhere. Without a root lockfile,
_workspace_root(web_dir) already returns web_dir, so the new
"() if npm_cwd == web_dir" branch correctly drops --workspace and the
assertion failed. Model a real workspace checkout instead: the single
package-lock.json lives at the root, so --workspace web scopes the install.

Also add the symmetric web regression test (web/ carrying its own lockfile =>
--workspace must be dropped and the install runs plainly from web_dir via
npm ci), matching the TUI coverage already in test_tui_npm_install.py.
