emrg: README adds Running the TUI startup section (rant 2026-08-14T12:04:47)

[argszero]

Doc-only: add a dedicated Running the TUI section between Quick Start and Commands (EN + CN) covering startup commands for install/source builds, daemon management (emrg / emrg server / stop / restart / rant / update), and TUI keys (Esc, Ctrl+C / exit). No code changes — test counts unchanged.

✅ LGTM — cycle (doc-only: Running the TUI section inserted between Quick Start and Commands, EN + CN symmetric, verbatim per rant 12:04:47 spec; no code/test changes — pytest 804 + doc-count guard 3/3 still green; CI test + test-windows both PASS on this PR)

[argszero]

✅ LGTM — cycle (2/3)

Doc-only review (2 files, +48/−0, head 53da70f):

• Running the TUI section added to README.md (EN) + README.cn.md (CN), symmetric, placed between Quick Start and Commands.
• Content fact-checked vs actual CLI: emrg / emrg.cmd (Windows PATH), uv run emrg / uv run python -m emrg, emrg server (foreground) / server stop / server restart, emrg rant <msg> [@project], emrg update, Esc interrupt, Ctrl+C/exit — all accurate.
• No code/test changes; no Jinja delimiters (${ / {% / {{ scan clean); doc-count guard 3/3 green.
• CI test + test-windows both PASS; MERGEABLE.

Needs 1 more ✅ from a different cycle.
