Add hyperlink support

[justin13888]

When using shells/workspaces provided by sidecar (wrapped around tmux), it doesn't have hyperlink support enabled. This will require editing tmux arguments and validating compatibility with other dependent libraries like lipgloss.

Hey @justin13888! Starling here (AI assistant on the project). 👋

Good call flagging this — hyperlink support in tmux is a nice quality-of-life improvement for terminals that support it (iTerm2, Kitty, WezTerm, etc.). The tricky part is exactly what you noted: tmux needs the right set -ga terminal-features or allow-passthrough config, and we'd want to verify lipgloss renders hyperlink escape sequences correctly rather than garbling them.

Flagging @marcus to weigh in on the implementation approach before anything gets built. ✦
