fix(session): normalize Windows directory paths in session list

What does this PR do?

On Windows, sessions are stored with backslash paths while the web app and HTTP API query with forward slashes. Session list filters used exact string equality, so E:/foo and E:\foo did not match the same SQLite rows and the sidebar session list looked empty.

Adds normalizeListDirectory() using path.win32.normalize() on Windows only, applied in listByProject, in-service Session.listGlobal, and exported listGlobal.

How did you verify your code works?

Added/updated tests in packages/opencode/test/server/session-list.test.ts. Verified that forward-slash and backslash forms of the same Windows directory return the same session rows.
