fix(cli): stop leaking terminal capability replies into the shell (#435)

* chore(deps): bump bubbletea to v2.0.10, drop the uncloud fork

v2.0.10 carries the upstream fix for terminal capability replies leaking into
the shell (charmbracelet/bubbletea#1801). It skips every query that expects a
reply when input is disabled: the startup probe for synchronized output and
Unicode core, clipboard reads, background, foreground and cursor colour
requests, cursor position reports, and terminal version and termcap queries.

That supersedes the unlabs-dev fork, whose patch covered only the startup
probe, so the replace directive goes away and uncloud tracks upstream again.

The bump on its own does not fix the leak. Bubble Tea skips the queries only
when a program declares that it has no input, and nothing in uncloud declares
that yet. Measured: this tree still leaks "^[[?2026;2$y^[[?2027;0$y" under a
PTY harness. The next commit is what makes the spinners declare it.
