v0.2.0

Added

• A GTO-style coach (lib/gto.js, settings -> coach style). The same spot, reasoned in ranges: EV per action over candidate bet sizes, with why-lines you can expand. Switchable from the coach window (简洁 | GTO) or the settings page.
• A real settings page (settings.section, id poker) with four groups: general on/off, AI opponents, coach style, about & updates. Connection test probes the configured endpoint with the values on screen.
• Check for updates (lib/update.js, settings -> about & updates): shows the installed version, the latest release, and offers a one-click update.
• AI opponents over any OpenAI-compatible endpoint. Optional seats are played by the configured endpoint; timeouts and invalid answers fall back to the built-in strategy.

Fixed

• The GTO coach recommended raises that could not happen, and said nothing new preflop - both reworked.
• The engine no longer offers a raise nobody can call.
• A toggle could make the sidebar entry vanish.

Changed

• Bot preflop ranges retuned against measurement (3000 six-handed hands: walks 23% -> 10%).
• playersBehind now measures position instead of seat-ring distance.
• Settings page layout: explanations live in row tooltips; the release check is automatic and the update is one click.
