v4.2.2: sync docs + example compose to wickworks v0.3.x Wickworks v0.3.0 went primitives-only (removed divergences + the signals/ package); v0.3.1 made camelCase canonical and tightened Bar volume validation. mt5-httpapi docs and the example compose pin were still on the old surface. - README intro + TA section drop divergences, add primitives-only disclaimer; rates/ta body table shows the flat indicators shape and marks recentBars inert in wickworks v0.3.x. - SKILL.md frontmatter + intro + bbands example + full indicator catalog rewritten to match wickworks v0.3.x reality (real registry names, 8 trader-meaningful categories, divergence row removed, missing alt-MAs added). - docker-compose.yml.example pin bumped v0.2.0 -> v0.3.1 so a fresh install no longer ships the pre-purification image. - Go client RatesTAQuery doc comment fixed (flat indicator shape; RecentBars marked inert). No signature change. No mt5-httpapi runtime code changed.
