refactor(cli): make dsh the sole terminal front door, drop RESUME_SESSION_ID

Remove the redundant dsh-tui-demo bin and the RESUME_SESSION_ID environment
variable, leaving dsh as the one terminal entrypoint.

The dsh-tui-demo package was a plugin (the TUI app bundle mounted by dsh's
config) plus a bin that booted a leaf cordis.yml — the same job `dsh [config]`
does. The bin, its ./bin export, its built-bin.e2e.ts, the tsdown bin entry,
and the now-unused dsh-app-boot dependency are removed; the package keeps its
plugin and invariant. demo:cordis, demo:code-mode, and the tui-agent and
cordis-agent keyless PTY smokes now launch through apps/cli/src/bin.ts with the
config as the positional argument. cli-demo/acp-demo/jsonrpc-demo keep their
bins (distinct surfaces).

RESUME_SESSION_ID was the only bridge from --resume into the shipped config;
--resume now provides the id on the boot context via ctx.provide(
RESUME_SESSION_ID_KEY, id), and the four configs read it as a bare identifier
through a quoted typeof-guarded !!js expression. The TUI resumeCommand fixtures
and docs move to `dsh --resume {session}`.

Agent Note and its Chinese pair updated; config-catalog regenerated.
