Krzysztof kuhy Rudnicki e06df74caf Coach tab: no sessions yet is a known state with how to start ... The exporter used to publish coach: null before the first session, so the tab printed "unknown" everywhere with no way forward. Now a missing or empty sessions dir exports empty problems/re-tests, every cluster at zero with its problems (slug, number, title, URL) and next, and a how_to block (commands, the 4-step method, first command). null stays for a real failure. how_to lives once in leetcode_coach/how_to.py; DOCS-how-to.md quotes it and a test fails on drift. The app's Coach tab shows a How to start card (monospace command box with copy), one card per cluster with tappable problems, re-tests with their command, and "unknown" + why only for a null section. Also fixes the done/solved key mismatch (the app read a key no exporter wrote).
