v0.34.0

Added

• Hook API: before_agent_start handlers can now return systemPromptAppend to dynamically append text to the system prompt for that turn. Multiple hooks' appends are concatenated.
• Hook API: before_agent_start handlers can now return multiple messages (all are injected, not just the first)
• New example hook: tools.ts - Interactive /tools command to enable/disable tools with session persistence
• New example hook: pirate.ts - Demonstrates systemPromptAppend to make the agent speak like a pirate
• Tool registry now contains all built-in tools (read, bash, edit, write, grep, find, ls) even when --tools limits the initially active set. Hooks can enable any tool from the registry via pi.setActiveTools().
• System prompt now automatically rebuilds when tools change via setActiveTools(), updating tool descriptions and guidelines to match the new tool set
• Hook errors now display full stack traces for easier debugging

Changed

• Removed image placeholders after copy & paste, replaced with inserting image file paths directly. (#442 by @mitsuhiko)

Fixed

• Fixed potential text decoding issues in bash executor by using streaming TextDecoder instead of Buffer.toString()
• External editor (Ctrl-G) now shows full pasted content instead of [paste #N ...] placeholders (#444 by @aliou)
