Add lines, functions, and statements at 80% alongside branches in both
the server (vite.config.ts) and client (vitest.client-coverage.config.ts)
coverage gates — branch-only thresholds allow misleadingly sparse tests to
pass the gate.
Also adds a plugin-sync comment to vitest.client-coverage.config.ts listing
the four Vite plugins mirrored from vite.config.ts.

Runs test:coverage (server v8 + client Istanbul) after tests, hard-gates
on both 80% branch thresholds, and uploads coverage/ as an artifact.

Sequential && prevents the ENOTEMPTY race on coverage/.tmp. Server
uses v8 via --project=server; client uses the standalone Istanbul config.

Vitest 4 silently ignores per-project coverage overrides in test.projects,
so a standalone vitest.client-coverage.config.ts provides the root-level
Istanbul coverage block that Vitest actually honours.
Root vite.config.ts retains the v8 coverage block (reportsDirectory:
coverage/server) for the server project. The client config writes to
coverage/client and instruments all .svelte and .svelte.ts files.

Istanbul instruments code at transpile time and works inside Chromium's
sandbox; v8 coverage is silently a no-op in browser mode.
