docs: related-tools section, language links, and RU wording polish

- Add a 'Related tools' section (EN + RU) introducing SIMple, SIMtrace
  Analyser and sigrok_iso7816_stream as independent tools.
- Cross-link the two READMEs (English/Russian) at the top.
- Russian: replace the 'pill' calque with 'button' (README_RUS + help-ru),
  and tighten the PC/SC-fallback, init-output and canonical-path wording.
- Bump the SW cache for the help-ru.html change.

 - **"Service not available" (0x8010001D) / reader gone after a `pcscd` restart** — the server recovers by itself: a watchdog revives pyscard's presence monitor and the next equip (automatic after re-insertion, or the **Equip** button) recreates the PC/SC transport (releasing the old link first).

A card removed while the server initializes at startup leaves it cardless with one line (no traceback), and the next insertion equips normally. The swallowed init error (with its traceback) is now printed as `AUTO-EQUIP: init output:`, and a card that is present but produced no card is a failure, not a silent "card gone". The watchdog re-arms with a doubling delay (5 s up to 60 s) while a card is present; a removed card clears the card state completely, so handlers answer "no card" instead of transmitting over the dead card.
