"""Deterministic static-analysis regression for Phase 08-03: persistent side
panel (R18). The extension JS can't run headless, so we assert the wiring
CONTRACT by source inspection (mirroring the 06/07 plans). ASCII-only output.

Proves:
  * content.js injects an idempotent left-docked iframe panel hosting
    popup/popup.html, with a collapse/dismiss toggle, handles TOGGLE_PANEL, and
    keeps EXTRACT_JD; it never disables page interaction globally.
  * manifest.json exposes the popup via web_accessible_resources, bumps the
    version to 1.5.0, and retains the content script + default_popup launcher.
  * popup.js keeps the background-owned run (ats_results + storage.onChanged +
    getCurrentUrlKey), adds launcher/embed awareness (TOGGLE_PANEL + window.top),
    and surfaces the 08-01 LaTeX compile-failure reason (pdf_error + compile_log).

Exit code: 0 when every assertion passes, 1 otherwise.
