Remove auto-cd functionality from wtp add command

[satococoa]

Summary

• Removes the automatic directory change behavior from wtp add command
• Simplifies the codebase by removing complex shell wrapper logic
• Makes behavior more predictable and explicit

Breaking Change

Before: wtp add feature/xyz would automatically cd to the new worktree
After: Users need to explicitly run wtp add feature/xyz && wtp cd feature/xyz

Changes

• Removed auto-cd logic from bash completion script
• Removed auto-cd logic from zsh completion script
• Removed auto-cd logic from fish completion script
• No documentation updates needed (feature was not documented)
• All tests pass

Migration Guide

Users who relied on the auto-cd behavior will need to update their workflow:

# Before (v1.1.x)
wtp add feature/new-feature  # Automatically cd's to new worktree

# After (v1.2.0)
wtp add feature/new-feature && wtp cd feature/new-feature

Test Plan

• Run go tool task dev - all tests pass
• Manually test wtp add command - creates worktree without changing directory
• Shell completion still works for all shells

This is the first step in the migration plan outlined in the Untitled.md document, preparing for the future wtp init-shell command architecture.

Summary by CodeRabbit

• Refactor
  • Simplified shell integration for the add command across Bash, Zsh, and Fish.
  • The shell no longer auto-navigates to the newly created worktree after running add.
  • Commands now execute without post-add directory changes; users should cd manually if desired.
  • Other completion features and cd helpers remain unchanged and continue to work as before.

Walkthrough

Removed the post-add auto-cd behavior from shell completion/integration for Bash, Zsh, and Fish in cmd/wtp/completion.go. The add path now simply invokes wtp "$@" without parsing arguments or attempting to cd. Other completion helpers and cd integration remain unchanged.

Changes

Cohort / File(s)	Summary
Shell completions (Bash/Zsh/Fish) cmd/wtp/completion.go	Deleted logic that, after wtp add, parsed args to find the new worktree and auto-cd into it; now defers to wtp "$@" only. Existing completion helpers (__branches, __worktrees, __worktrees_cd, cd integration) unchanged.

Poem

I hop through shells—bash, zsh, and fish—
No magic leaps to folders on a wish.
Add, then pause; I twitch an ear—
The cd is yours to engineer.
Carrot-commit made crisp and clean,
A simpler trail across the green. 🥕
