Subject: [PATCH] terminal: copy/paste keys, a pane context menu, opt-in
 copy-on-select (#131)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Selecting text in the live pane was unreliable and copying was a side effect of it:
every mouseup with a selection overwrote the clipboard, and a right-click — the obvious
way to reach Copy/Paste — had nothing to open. This is the first slice of #131, in the
order written there.

- Ctrl+Shift+C / Ctrl+Shift+V on Linux and Windows, Cmd+C / Cmd+V on macOS, through
  attachCustomKeyEventHandler. The handler returns false for a chord it handled: without
  that xterm forwards it to the TUI, so Ctrl+Shift+C would both copy and send ^C to the
  running agent. Plain Ctrl+C is untouched, so SIGINT still reaches it.
- The pane answers right-click itself: Copy / Paste / Select all / Copy on select.
  Copy is disabled while nothing is selected, and a right-button release no longer copies
  first, so the selection the user just made is what Copy acts on. Paste reuses the
  existing bracketed-paste path (pasteToTerminal), which never auto-submits; it gained an
  optional { silent } so a paste from the keyboard does not toast.
- Copy-on-select is now a setting, off by default, toggled from that menu and remembered
  in localStorage. It used to be unconditional and the only way to copy.
- macOptionClickForcesSelection: true, rightClickSelectsWord: false, and a title on the
  pane saying Shift+drag selects when the app reports mouse events.

Tests: test/terminal-clipboard.test.js runs the helpers and _createTerminal itself in a
vm with a fake xterm, element and clipboard — chords per platform, Ctrl+C passthrough,
copy-on-select default and persistence, the menu model, and the mouseup/contextmenu
wiring. 12 checks. test/composer-terminal.test.js keeps its assertions but two of them
described the old mouseup shape (no event argument, unconditional copy), so they are
re-pointed rather than dropped.

Verified: every test module that reads public/index.html passes (20 modules, including
i18n completeness at 139 checks with the 6 new keys in all 5 languages); the three that
need better-sqlite3 pass under Node 24, which is what it was built for; all three inline
script blocks of index.html parse.

Not in this slice: the addons (web-links, unicode11, search, clipboard, webgl) and the
mobile proposals in the second comment on the issue. They change rendering or need
vendored files, so they get their own PR.

+//     mouseup never copies;
+//   - the context menu lists Copy / Paste / Select all / Copy on select, with Copy
