fix: typecheck after PR train merge

- Add revealed prop to TabContentMemoKey + comparator (PR #94 threads
  it through TabContent but the memo key lacked it).
- Destructure revealed in TabContent body.
- openpath-intercept test: provide no-op revealInExplorer default.
- prefs test: add browserAllowedLoopback to setPrefs calls (PR #69).
- smoke test: drop duplicate encodeHtmlUrl import (PR #193 dup).
- index.ts: null-guard ptyManager in session/disposed (PR #130 revert).
- locales-fr/nl: avoid unescaped apostrophes in loopback desc (PR #69).
