feat(i18n): the Run button family, and the Help modal and shortcut overlay leftovers, in Chinese

Owner request: translate "Run SH" and the rest of the Run family, plus
the two leftovers from the last report.

Run: one pattern turns "Run <code>" (Run CC, Run SH, Run OC, Run CX ...,
and any registry CLI's shortBadge) into "运行 <code>"; the mode codes and
product names stay, and exact entries still win ("Run Shell" was already
运行 Shell, "Run OMP" 运行 OMP, "Run PI" takes the "Run Pi" entry). New
entries: "Terminal / Shell" (the run menu's shell item) and "Send Enter"
(the phone toolbar's Enter button title). The phone overview's Run button
already showed 运行 beside a mode word kept as typed.

Help modal and shortcut overlay: "Tabs", "Toggle Session Sidebar", both
"Copy Selection" rows, "Focus Tabs", and "Wheel" (滚轮, a mouse input like
Click). Key names stay English: the Help modal's Home key, and every key
the overlay renders, now carry data-i18n-skip, because "Home" is also a
dictionary word (the Home button) and showed as 主页 in the key column.

The invariants' paneExit section gains the badge's translation rule
(from the previous commit): its updates compare with the remembered
English, never the DOM.

Tests: i18n-exit-run-help covers every Run label _applyRunMode can show
(its hard-coded ones and Run <shortBadge> for every stock CLI), the
toolbar titles, the Help modal through the real translator in JSDOM (no
English outside the key column, the Home key kept while the word Home
elsewhere still translates, Wheel translated), every shortcut registry
group and label, and that the overlay's keys are skipped.
