fix(e2e): wire e2e into pre-commit and fix flaky upstream tests

Add `e2e` as a dependency of `pre-commit` and `pre-commit-full` in the
justfile so `just pre-commit` now runs Playwright e2e tests automatically.

In the fork submodule: fix the terminal toggle keybind test (defocus
terminal between toggles), and skip two sidebar session-link tests that
are incompatible with our git submodule environment due to worktree path
mismatch from `git rev-parse --git-common-dir`.
