fix: stop intercepting plain c in auth shell

[CoderLuii]

Summary

• stop consuming plain lowercase c in the minimal auth shell path
• keep the auth URL copy shortcut on an explicit Shift+C chord instead

Testing

• validated in HolyClaude integration flow while reproducing the broken plain-text c input issue

Summary by CodeRabbit

• Bug Fixes
  • Updated the keyboard shortcut for copying authentication URLs in the shell terminal. The shortcut now requires pressing Shift + C instead of the "c" key, preventing accidental triggers. Standard copy and paste shortcuts remain unaffected.

📝 Walkthrough

Walkthrough

Updated keyboard shortcut in the shell terminal hook from triggering on lowercase "c" to requiring Shift + "C" for initiating auth URL copy functionality in plain-shell flows.

Changes

Cohort / File(s)	Summary
Keyboard Shortcut Update src/components/shell/hooks/useShellTerminal.ts	Modified custom key handling to require Shift + "C" instead of case-insensitive "c" for auth URL copy trigger.

Poem

🐰 A shift was made, precise and keen,
Now "C" needs company, if you know what I mean!
Shift and uppercase dance in harmony,
Auth URLs copy with specificity!
The shell speaks clearer, as shells should be. ✨
