fix(lint): address remaining unicorn v65 violations and pin React to 19.2.4

- prefer-includes: host-errors.ts (error._tag chain → .includes())
- prefer-includes: lib/core/auto-agent-flags.ts (same find() pattern as frontend-lib)
- prefer-includes: app-terminal-session-handlers.ts (split 3-undefined chain into
  individual early returns to preserve TypeScript narrowing)
- consistent-compound-words: rename isUnixUserName→isUnixUsername,
  sshUserNamePatternDescription→sshUsernamePatternDescription,
  unixUserNamePattern→unixUsernamePattern across frontend-lib/core/domain.ts,
  frontend-lib/core/command-builders-shared.ts, lib/core/domain.ts,
  lib/core/command-builders-shared.ts, lib/shell/config.ts
- React: re-pin react/react-dom to 19.2.4 in root overrides, packages/app,
  packages/terminal (Renovate bumped them back to 19.2.7)

All 448 tests pass locally.
