Description

Updates the dependencies that Dependabot proposed in #30, each in the module that uses it. #30 was opened before the demo dependencies moved to examples/go.mod, so it put Bubble Tea and gopsutil back in the root module and now conflicts with main. Dependabot cannot recreate it because the dependabot.yml entry it came from no longer exists.

• Root module: github.com/charmbracelet/x/ansi 0.11.8 to 0.11.9, which raises github.com/mattn/go-runewidth to 0.0.27.
• examples module: charm.land/bubbletea/v2 2.0.10 to 2.1.1, github.com/shirou/gopsutil/v4 4.26.8 to 4.26.10, x/ansi 0.11.9, and their indirect updates.
• go list -m all in the root still lists neither Bubble Tea nor gopsutil.

Issues

Replaces #30.
