piu v0.1.45

New Features

• MCP Hook Management — Create, list, update, and delete response hooks via MCP tools (create_hook, list_hooks, get_hook, update_hook, delete_hook). Skills can now set up complete auth token flows programmatically: create a login request, configure a hook to extract the token, execute login, and the token is captured into variables automatically.
• update_variable MCP tool — Update a single environment variable by key directly via MCP.
• set_env_variables returns full records — Now returns stable variable IDs and full metadata after upsert, enabling downstream hook targeting without a separate lookup.
• get_request includes hooks_associated — Requests now surface any variable-linked hooks in their detail response.

Bug Fixes

• Hook execution in MCP — execute_request now fires response hooks via process_hooks_headless(), so hooks trigger when requests are sent via MCP tools (not just the desktop UI).
• Variable upsert preserves IDs — set_env_variables uses upsert-by-key semantics, preserving variable IDs and hook target foreign keys across updates (no more orphaned hook targets on re-sync).
• Transactional hook writes — create_hook and update_hook are now wrapped in transactions to prevent partial state on failure.
• Direct hook lookup — Added get_hook_by_id query for reliable single-hook retrieval.

Maintenance

• Updated dependencies (bun.lock, Cargo.lock)
• Updated piu-mcp skill to document all 57 tools including new Hooks and Variables sections
• Updated piu-hyperf-sync skill with hook setup step in Phase 4 and match_paths on variables
