fix: handle exec init to prevent TUI on re-source

[zzzhizhia]

Summary

Fix 1: Handle exec init subcommand

• When re-sourcing ~/.zshrc, the try shell function is already defined, so try init ~/path routes through the wrapper as try exec init ~/path
• The exec handler didn't have a case for init, causing it to fall through to the default TUI selector — triggering an unwanted interactive UI with search term init-/path/to/tries
• Added when 'init' to the exec subcommand dispatch so it correctly delegates to cmd_init!
• Added regression test in spec/tests/test_03_commands.sh

Fix 2: Invoke script directly instead of via /usr/bin/env ruby

• The init shell function used /usr/bin/env ruby to invoke the script, which could resolve to the wrong Ruby version (e.g. system Ruby 2.6 lacking Data.define support)
• Changed to invoke the script path directly, letting the shebang determine which Ruby to use
• script_path is always File.expand_path($0) — the absolute path of the running script — so direct invocation is safe
• Applied to all three shell snippets: bash/zsh, fish, and PowerShell

Reproduce

# In ~/.zshrc:
eval "$(try init ~/Developer/tries)"

# First source works fine, second triggers TUI:
source ~/.zshrc  # ← interactive selector pops up

Test plan

• try init ~/path still outputs shell function definition
• try exec init ~/path now also outputs shell function definition (instead of opening TUI)
• source ~/.zshrc can be run multiple times without triggering the selector
• Init snippet no longer contains /usr/bin/env ruby, uses script path directly

Pull request overview

This PR fixes a bug where re-sourcing ~/.zshrc (when the try shell function is already defined) causes try init ~/path to be routed as try exec init ~/path, which previously fell through to the default TUI selector instead of outputting the shell function definition.

Changes:

• Added a when 'init' case to the exec subcommand dispatch in try.rb to correctly delegate to cmd_init!
• Added a regression test verifying exec init outputs the shell function
