fix(install): also patch psutil on Termux fresh-install path

The Termux update path (PR #22814) prebuilds psutil from a marker-patched
sdist so 'platform android is not supported' doesn't kill it. The same
psutil setup.py error blocks fresh installs via scripts/install.sh — only
the update path was wired up. Without this, a brand-new Termux user can't
get past the very first 'pip install -e .[termux-all]' call.

- New scripts/install_psutil_android.py — standalone version of the same
  patcher hermes_cli/main.py uses, callable from bash.
- scripts/install.sh detects sys.platform == 'android' and runs the
  patcher before pip install.
- TODO note added to both copies pointing at upstream
  https://github.com/giampaolo/psutil/pull/2762; remove both when that
  ships.

Note: we keep psutil as a base dep on Android (do not adopt the proposed
sys_platform != 'android' marker in pyproject). Removing it would crash
five unguarded 'import psutil' sites at runtime
(tools/code_execution_tool.py, tools/tts_tool.py, tools/process_registry.py
(2x), gateway/platforms/whatsapp.py).
