Add option to hide verbose Bash command output

Hi,

After a recent update, Claude Code now displays detailed output for every Bash command
execution:

⏺ Bash(echo -e "\n## 10:25 Session ended\n- User moving to GPT project\n- ...")
⎿ (No content)

While this transparency is appreciated, it significantly reduces readability,
especially when Claude Code performs frequent operations like logging or file updates.

Proposed Solution

Add a command-line flag to control verbosity:

• --quiet or --verbose=false to hide Bash command details
• Keep current behavior as default for users who prefer transparency

Use Case

Users who run Claude Code for extended sessions with frequent file operations would
benefit from cleaner output without sacrificing functionality.

Current Workaround

None available - the verbose output cannot be disabled.
