fix(links): open links on Ctrl+click on Windows and Linux

The link modifier was `mods.platform`, which gpui maps to ⌘ on macOS but
to the Win/Super key elsewhere — a key the OS mostly swallows, so on
Windows and Linux neither the hover underline nor click-to-open could be
triggered at all. `config.json`'s own docs already promised "⌘/Ctrl-click";
this is the implementation catching up.

Use `Modifiers::secondary()` (⌘ on macOS, Ctrl elsewhere) at all three
sites: the click handler, the hover probe, and the app-level modifier
tracking that pushes the state down to background panes. Not
`platform || control` — that would steal ⌃-click on macOS, where it means
"right click".

Ctrl+click still falls through to mouse-tracking TUIs when there's no
link under the cursor, since `open_link_at` reports whether it consumed
the click.

Fixes #183
