fix(termux): prebuild psutil compatibility shim in setup-hermes.sh

[bradlishman]

What does this PR do?

Fixes setup-hermes.sh (the manual dev quick-setup script) so it doesn't silently produce a broken install on Termux/Android.

On Termux, setup-hermes.sh currently jumps straight from creating the venv to pip install -e ".[termux]" -c constraints-termux.txt. Because upstream psutil's setup.py rejects sys.platform == "android" before the build even starts, that install fails on psutil with platform android is not supported — the exact symptom in #31415. The script's own -e (set -e) doesn't catch this because the pip call is chained with || into a fallback that also fails, and the overall script still exits 0, leaving a venv containing only pip/wheel/setuptools and no actual hermes command.

scripts/install.sh (the one-line curl | bash installer) already works around this: it prebuilds psutil via the repo's own scripts/install_psutil_android.py shim before the [termux] install. setup-hermes.sh never got the equivalent step, so anyone following "Quick setup for developers who cloned the repo manually" on Termux hits this.

Related Issue

Fixes #31415

Note: #44390 (open) already fixes the documented manual step-by-step guide in website/docs/getting-started/termux.md to include the psutil shim step. That guide never mentions setup-hermes.sh, so this PR is a separate, non-overlapping fix for the convenience script itself — confirmed no open PR currently touches setup-hermes.sh's Termux branch.

Type of Change

• 🐛 Bug fix (non-breaking change that fixes an issue)

Changes Made

• setup-hermes.sh: on Termux, detect sys.platform == "android" and run scripts/install_psutil_android.py (mirroring install.sh's existing guard and warning message) before the [termux] pip install.

How to Test

1. On a fresh Termux checkout of this branch: rm -rf venv && ./setup-hermes.sh
2. Without this fix, the install log shows ERROR: Failed to build 'psutil' when getting requirements to build wheel and the script still exits 0 with venv/bin/ containing no hermes entry point.
3. With this fix, Android Python detected: prebuilding psutil compatibility shim... prints before the [termux] install, pip install -e ".[termux]" succeeds, and hermes --version / hermes doctor work afterward.

Checklist

Code

• I've read the Contributing Guide
• My commit messages follow Conventional Commits (fix(scope):)
• I searched for existing PRs to make sure this isn't a duplicate (see note above re: fix(termux): align manual psutil install with supported installer #44390 / fix(termux): complete native install, TUI, and Desktop support #67163 — neither touches setup-hermes.sh)
• My PR contains only changes related to this fix/feature (no unrelated commits)
• I've tested on my platform: Termux on Android (aarch64)

Documentation & Housekeeping

• N/A — no config keys, architecture, or tool schema changes; website/docs/getting-started/termux.md doesn't reference setup-hermes.sh so no doc update needed here

Related to #31415 and #44390: this repairs setup-hermes.sh itself, whereas #44390 covers the manual Termux guide.

Thanks for covering the separate setup-hermes.sh path.

Problems

• The reported exit-0 behavior is not supported by the current script's set -e at setup-hermes.sh:20; a matching false || { false; } Bash reproduction exits 1. The substantive gap remains real: setup-hermes.sh:196-203 reaches the Termux pip install without the Android psutil shim.

Suggested changes

• Update the PR description/test expectation to target the missing prebuild ordering rather than a successful exit after two failed package installs. The added invocation otherwise mirrors the established installer implementation at scripts/install.sh:1450-1455.

Automated hermes-sweeper review.

Summary

Three PRs address or reference #31415 across distinct Termux installation paths: #22901 added the Android psutil shim to the supported installer and update flow, #44390 adds the missing shim and 32-bit Rust-target guidance to the manual documentation, and #72571 invokes the existing shim from the cloned-repository quick-setup script.

Related pull requests

• #22901 [merged] partial — (+281/-32) — merged reference implementation: it introduced scripts/install_psutil_android.py and wired the psutil prebuild into fresh installs and updates, directly handling psutil's Android platform rejection; it remains relevant because the other PRs extend that established workaround to paths it did not cover.
• #44390 best fix — (+120/-11) — keep open with a salvage path: the diff places the existing psutil shim before pip installation in both manual guides, adds the reported armv8l Rust-target workaround, and tests those ordering and architecture invariants. This matches the keep_open review on #44390 and addresses the documentation path rather than duplicating the installer implementation.
• #72571 partial — (+14/-0) — keep open with a salvage path: the diff adds the established Android-only psutil prebuild before setup-hermes.sh's Termux pip command, covering a separate executable path from #44390. This matches the keep_open review on #72571, but the PR description should drop its unsupported claim that both failed installs leave the script exiting 0; the verified gap is the missing prebuild ordering.

Suggested consolidation

Keep #44390 open for the manual-guide and regression-test salvage path, and keep #72571 open for the separate setup-hermes.sh salvage path after correcting its exit-status rationale. #22901 is the merged reference implementation, not a duplicate to revisit; #44390 and #72571 should not be closed as duplicates because they modify non-overlapping user paths.
