Two stale Spanish smoke assertions still expected English page titles
for PDF Extractor and Reconciler — the i18n work landed real
translations ("PDF a CSV", "Reconciliar dos archivos"), so refresh the
expected substrings and the surrounding comment.
Add new coverage for the help-popover feature:
- TestHelpPopoverKeys (test_lang_packs): every tool_id resolves a
non-empty tools.<id>.help_md in BOTH packs; help.button_label and
help.missing_body resolve in both.
- TestDescriptionCopy (test_tools_registry): every Tool.description
non-empty and under 120 chars — pins the post-jargon-scrub copy
so future drift back into multi-clause prose is loud.
- TestRenderToolHeaderSmoke: render_tool_header is callable, listed
in components.__all__, and every i18n key it touches resolves in
both packs. Runs without a Streamlit script context.
Suite: 2427 passed (+9 new), 91 skipped.

Introduces ``src/i18n`` with a tiny JSON-backed t() lookup, an in-session
language preference, and a sidebar selector wired through
``hide_streamlit_chrome`` so every page picks up the same picker. Covers
home, tool cards, findings panel, gate, shutdown, and pickup banner
strings. Tests pin pack parity and the farewell-overlay JS escape so
future packs can't silently regress.
