* feat(desktop): isolate pnpm dev:desktop per worktree (MUL-3724)
Two worktrees could not run pnpm dev:desktop at once: both grabbed the
renderer port 5173 and the single-instance lock keyed by the app name
"Multica Canary". The env hooks to override each already existed
(DESKTOP_RENDERER_PORT in electron.vite.config.ts, DESKTOP_APP_SUFFIX in
src/main/index.ts) but nothing derived per-worktree values.
A new dev launcher (scripts/dev.mjs) derives both from the worktree path
for linked worktrees only — reusing the same cksum%1000 offset as
scripts/init-worktree-env.sh, so renderer port is 5173+offset and the app
becomes "Multica Canary <folder>" with its own userData/lock. The primary
checkout is untouched; explicit env vars still win. Backend targeting is
unchanged (apps/desktop/.env*). Also: brand-dev-electron honors the suffix,
turbo globalEnv passes it through, and CONTRIBUTING documents the flow.

* fix(desktop): make worktree dev port/suffix collision-safe (MUL-3724)
Addresses code review on #4598:
- Renderer port base 5173 → 5174 so a worktree whose offset is 0 (e.g.
cksum("/tmp/multica-3494") % 1000 === 0) no longer collides with the
primary checkout's default 5173.
- DESKTOP_APP_SUFFIX is now "<folder>-<offset>" instead of just the folder
name, so worktrees that share a basename at different paths (or names that
slug to the same fallback) get distinct single-instance locks. Without it
the second Electron was still blocked by the shared lock.
- Tests: offset-0 port guard, and same-basename-different-path disambiguation.
