Merge branch 'master' into worktree/dsh-arg-parser

Integrate the Commander argument adapter with master's safe session-resume
feature and dsh web --dev flag.

- args.ts: add --dev to the web parser.
- tui.ts: keep master's process.execve in-place resume handoff, but take the
  adapter's parsed (config, resume); inject the resume id through boot's
  prepare(ctx) hook via ctx.provide(RESUME_SESSION_ID_KEY, id) instead of the
  RESUME_SESSION_ID env var; rebuild the re-exec argv as `dsh --resume <id>`.
- app-boot: drop master's replaceResumeArg (no longer needed) alongside the
  already-removed parseResumeArg; add RESUME_SESSION_ID_KEY.
- the four tui-agent/cordis configs read the ctx-provided resumeSessionId via a
  typeof-guarded !!js expression, so resume needs no env var.
- web.ts: keep master's client roster and --dev watch, take parsed host/port/dev.
