Usage: task-init [--help] [--force] [impl] [impl-options]

Sets up the current git repo for an agentic-workflow implementation.
With no impl argument, shows an interactive TUI selector (fzf or gum) if available,
or falls back to a two-step numbered menu.

Implementations:
  claude-jira    Claude Code + Jira (Atlassian MCP)
                 Options: --site URL, --key PROJ, --board NAME, --force
  claude-notion  Claude Code + Notion MCP
                 Options: --force, --help-ids
  claude-gh      Claude Code + GitHub Projects (gh CLI)
                 Options: --force
  claude-local   Claude Code + local markdown task tracking (no external tracker)
                 Options: --force
  kiro-notion    Kiro CLI + Notion MCP
                 Options: --force, --help-ids
  kiro-gh        Kiro CLI + GitHub Projects (gh CLI)
                 Options: --force
  kiro-local     Kiro CLI + local markdown task tracking (no external tracker)
                 Options: --force

Global options:
  --force     Overwrite existing config files (passed through to impl)
  -h, --help  Show this help

Examples:
  task-init
  task-init claude-gh
  task-init kiro-gh --force
