Summary

• Add wt.remover config key and --remover CLI flag to replace git worktree remove with a custom command (e.g. trash-put)
• After the custom remover runs, git worktree prune cleans up git's internal tracking automatically
• Worktree path is passed safely via shell positional argument ("$1") to handle spaces and special characters

Motivation

git worktree remove uses rm -rf internally, which can be slow for large worktrees. Trash commands like trash-put move directories to the system trash instantly, providing a much faster alternative.

Usage

# Persistent via git config
git config wt.remover "trash-put"

# One-off via flag
git wt -D --remover "trash-put" my-branch

Files Changed

• internal/git/config.go: Added configKeyRemover constant, Remover field to Config, loading logic in LoadConfig()
• internal/git/worktree.go: Added RunRemover() and PruneWorktrees() functions
• cmd/root.go: Added --remover flag, flag override in loadConfig(), remover branch in deleteWorktrees(), help text
• e2e/config_test.go: Added TestE2E_Remover with 6 subtests, updated completion flag list

Test Plan

• go build ./... compiles cleanly
• go vet ./... passes
• 6 new e2e subtests pass: flag, config, flag_overrides_config, failure_prevents_deletion, prune_cleans_up, path_with_spaces
• TestE2E_Complete passes with --remover in expected flags

Closes #143
