fix: restore sans-serif for inputs; make Cmd+K work in capture phase

## Font rendering
Pre-sync, the fork had only `pre, code, textarea, input` selectors
using Geist Mono when code/terminal context demanded it, but the recent
sync collapsed all four into a single rule that applied the monospace
stack to *every* <input> in the app. The command palette search, model
picker trait inputs, settings binary/server URL fields, etc. all rendered
in Geist Mono, which is what produced the 'broken font' look.

Narrow the rule back to `pre, code` (and `textarea` in code-focused
contexts inherits naturally). Regular inputs now use the body font
(DM Sans).

## Cmd+K shortcut
The commandPalette.toggle keydown handler in CommandPalette.tsx used
the bubble phase, which means xterm (when terminal has focus) or a
contenteditable composer could swallow Cmd+K before it reached the
window listener. Switch the listener to capture phase — matches
upstream's CTRL+J fix for terminal.toggle (pingdotgg#2113). The project picker
already lives inside the command palette (filesystem browse API +
command-palette project picker from pingdotgg#2024); this restores access to it
via the shortcut.
