test(log): avoid global logger module mocking

Replace the effect-log tests' global util/log module mock with local spies on Log.create so the logger compatibility tests no longer leak into unrelated unit suites. Keep the coverage for routing, annotations, spans, and cause formatting while allowing the full package test workflow to run cleanly.

+### Terminal Tests
+
+- In terminal tests, type through the browser. Do not write to the PTY through the SDK.
+- Use `waitTerminalReady(page, { term? })` and `runTerminal(page, { cmd, token, term?, timeout? })` from `actions.ts`.
+- These helpers use the fixture-enabled test-only terminal driver and wait for output after the terminal writer settles.
+- Avoid `waitForTimeout` and custom DOM or `data-*` readiness checks.
+
 ## Writing New Tests
 
 1. Choose appropriate folder or create new one
 2. Import from `../fixtures`
 3. Use helper functions from `../actions` and `../selectors`
-4. Clean up any created resources
-5. Use specific selectors (avoid CSS classes)
-6. Test one feature per test file
+4. When validating routing, use shared helpers from `../actions`. Workspace URL slugs can be canonicalized on Windows, so assert against canonical or resolved workspace slugs.
