Summary

Remove the Rich [link=...] markup from the project URL console output, replacing it with plain [cyan] styling.

Problem

Rich's [link=...] markup emits OSC 8 terminal hyperlink escape sequences. These escape sequences break output in Google Colab and IPython environments — particularly when the project URL is printed from a background thread during logfire.configure(), the escape sequences interfere with Colab's output handling and can swallow subsequent print() output entirely.

See the detailed investigation in #1267.

Fix

• Replace [link={url} cyan]{url}[/link] with [cyan]{url}[/cyan] in print_token_summary()
• Remove the now-unnecessary custom Theme and Style imports from _print_summary() (they were only used to customize the link color)

The URL remains visible and cyan-colored in terminals that support Rich markup, but no longer emits hyperlink escape sequences.

Test plan

• All existing tests in test_configure.py and test_cli.py pass (162/162) — they assert on the rendered text via capsys, which is unchanged
• Full non-Docker test suite passes (1262 passed)
• ruff format, ruff check, and pyright all pass
• All pre-commit hooks pass

Fixes #1267

Summary by cubic

Remove Rich hyperlink markup from the project URL output. Use plain cyan text to avoid OSC 8 sequences that break Google Colab and IPython output.

• Bug Fixes
  • Use [cyan]{url}[/cyan] instead of [link={url} cyan]{url}[/link] in print_token_summary().
  • Remove custom Theme/Style; use default Console.
  • URL stays visible and colored; notebook output is no longer swallowed.
