fix(desktop): resolve Electron dist from workspace

[rasitakyol]

Summary

• point desktop electronDist at the Electron package installed under apps/desktop/node_modules
• update desktop CLI and installer Electron-dist recovery paths to check the desktop workspace instead of the repo root
• add a regression test locking electronDist to the workspace install location

Test Plan

• uv run --extra dev pytest tests/test_desktop_electron_pin.py -q
• ./venv/bin/python -m py_compile hermes_cli/main.py
• bash -n scripts/install.sh
• pwsh parser check for scripts/install.ps1 (if pwsh is available)
• ./venv/bin/hermes desktop --build-only --cwd /Users/rasitakyol/Documents/GitHub/aicoolies-research

Duplicate of #48003 — same fix (point desktop electronDist at the workspace-local apps/desktop/node_modules/electron/dist install, plus CLI/installer Electron-dist recovery paths), with an identical tests/test_desktop_electron_pin.py regression test. The changed files here are a subset of #48003 (the earliest open PR with this approach; #48012 was already marked a duplicate of it). All three target the build-after-update electronDist-resolution bug tracked in #47917.

Thanks for checking. Confirmed this is a duplicate of #48003 and #48003 is the broader/canonical fix for #47917. Closing this PR in favor of #48003.
