security: fix improper string trimming via xargs#4
Conversation
The use of `xargs` to trim whitespace from branch names was vulnerable to failure when the branch name contained a single quote (e.g., `branch'quote`). In such cases, `xargs` would exit with an "unmatched single quote" error, preventing the deletion of the worktree. This commit replaces `xargs` with the Bash builtin `read -r`, which safely trims leading and trailing whitespace without interpreting quotes or other special characters. 🎯 **What:** Replaced `xargs` for string trimming in `bin/wt`.⚠️ **Risk:** Branch names with single quotes would cause `wt` to fail during deletion actions. 🛡️ **Solution:** Use `read -r branch <<< "$branch"` for robust whitespace trimming.

The
bin/wtscript usedxargsto trim whitespace from the branch name extracted from aDELETE:selection. However,xargsinterprets quotes by default, causing it to fail with "unmatched single quote" if the branch name contains a single quote (which is valid in git).I've replaced this with
read -r branch <<< "$branch", which uses the Bashreadbuiltin's default behavior of trimming leading/trailing whitespace without interpreting any characters in the string. This is both more secure and more efficient as it's a shell builtin.Verified the fix by testing the logic with branch names containing single quotes and whitespace.
