suppress bold rendering in terminal to keep cell grid stable

Flutter falls back to synthetic bold when JetBrainsMono-Bold isn't
registered, and synthetic bold drifts glyph advance widths enough
to break the monospace cell grid (cursor block lands between
characters, prompts wrap mid-word). Color is enough to convey
emphasis in TUIs; semantic italic and underline still render.

Also drop the temporary `tmux -L clide kill-server` from the
install target — the rapid-iteration loop is no longer needed.

+- Terminal cell grid no longer drifts on bold text — bold rendering
