chore: drop the unanchored workspace/ ignore rule that hides web-shell sources (#13155)

* chore: drop the unanchored workspace/ ignore rule that hides web-shell sources

The bare `workspace/` line under the brand-builder section matches every
directory named workspace at any depth, including the tracked source tree
packages/web-shell/client/daemon/workspace/. Its 34 files are tracked but
ignored, so a new file there never shows in git status and git add -A
skips it silently (a test in #13154 was nearly left out this way).

Nothing in the repo creates a workspace/ directory: the desktop brand
builder writes to brand-builds/, which stays ignored. The line arrived in
a squashed history import (99fd76553e), so its original intent cannot be
recovered from git.

* style(web-shell): format the two daemon/workspace tests prettier never saw

Prettier honours .gitignore, so the old bare `workspace/` rule also kept
packages/web-shell/client/daemon/workspace/ out of the formatting gate.
With the rule gone the gate checks the directory and flags these two
files; this is prettier --write output only.
