refactor(web-test): run.mjs распилен по cli/ (1258 → 65 LOC entry)

Внутренности move в cli/:
- util.mjs — out/die/json/readBody/readStdin/elapsed/elapsed2/slugify/formatDuration/xmlEscape/interpolate/printSteps/usage
- session.mjs — SESSION_FILE, loadSession, cleanup
- exec-context.mjs — buildContext, buildScopedContext, executeScript
- server.mjs — handleRequest (HTTP сервер в процессе start)
- commands/{start,run,exec,shot,stop,status,test}.mjs — по одной команде на файл
- test-runner/assertions.mjs — createAssertions (ctx.assert API)
- test-runner/severity.mjs — SEVERITY_RANK/LEVELS, buildSeverityIndex, resolveSeverity
- test-runner/reporters.mjs — writeAllure, allureStep, syncAllureExtras, buildJUnit
- test-runner/discover.mjs — discoverTests, resetState

run.mjs остался публичным entry-point с CLI-парсингом и dispatcher'ом.
Регресс tests/web-test/ зелёный (19/19, 9m 28s).
