fix(install): tokenize before ALL_RUNTIMES_OPTION check + isolate HERMES_HOME in test

Browse Source 
Two CodeRabbit findings on PR #2920:

1. parseRuntimeInput previously only matched the bare "16" exactly for
   the all-runtimes shortcut. Inputs the prompt explicitly encourages —
   "16,", "16 1", "1,16" — fell through to per-token parsing and
   silently installed only Claude or a partial subset. Move the
   ALL_RUNTIMES_OPTION check after tokenization so any token equal to
   "16" expands. Added regression coverage in
   tests/multi-runtime-select.test.cjs for the four mixed-input forms.

2. The "maps Hermes to ~/.hermes for global installs" test invoked
   getGlobalDir('hermes') without isolating HERMES_HOME. On a developer
   machine that exports HERMES_HOME the assertion would fail even
   though getGlobalDir was behaving correctly. Save/clear/restore the
   env var around the assertion, mirroring the pattern the later
   describe block already uses.

Full suite: 6128/6128 pass.
