v0.3.60

Added

• Inter-extension event bus — $pi->events(), upstream's pi.events: pub/sub channels (on() returning an unsubscribe closure, emit(), clear()) shared across all extensions of a load, with error isolation so one handler throwing does not break others.
• Full lifecycle hook events — tool_execution_start, tool_execution_update (streaming tool deltas), tool_execution_end, session_compact_failed (with reason, abort flag, and error message), user_bash (intercepting typed !command), and input (intercepting user input before skill/template expansion).
• Input transform & interception — InputEvent & InputEventResult (continue, transform, handled), fired before prompt expansion and during queue steering/follow-up, chaining text/image modifications across extensions.
• User bash command interception — UserBashEvent & UserBashEventResult: extensions can execute commands on remote hosts/containers and return BashExecution without falling back to local execution.
• Active tool loadout management — ToolLoadout, unifying tool filtering across session creation, /reload, and runtime; $pi->setActiveTools(), $pi->getActiveTools(), and $pi->getAllTools().
• Extension tool execution — $ctx->executeTool($name, $args): runs tools on an extension's behalf through schema validation and tool_call permission guards.
• Context usage and session control on $ctx — $ctx->getContextUsage() (ContextUsage with tokens, contextWindow, and percent), $ctx->getSystemPrompt(), $ctx->isProjectTrusted(), $ctx->mode(), $ctx->thinkingLevel(), $ctx->compact(), and $ctx->shutdown().
• Rich extension UI capabilities on $ctx->ui — pasteToEditor(), setTitle(), setWorkingMessage(), setWorkingVisible(), setHiddenThinkingLabel(), getToolsExpanded(), setToolsExpanded(), setWidget(), setHeader(), setFooter(), getAllThemes(), getTheme(), setTheme(), and onTerminalInput().
• Extension keyboard shortcuts — $pi->registerShortcut($key, $handler, $desc): custom shortcuts bound on the editor, executed in a fiber with context, and displayed in /help.
• Markdown transformers — $pi->registerMarkdownTransformer($transformer): transforms user and assistant Markdown before rendering in transcript.
• Tool renderers — $pi->registerToolRenderer($resolver): onion-middleware chain allowing extensions to customize call and result rendering for both built-in and custom tools.
• Custom entry renderers — $pi->registerEntryRenderer($customType, $renderer): draws custom session tree entries in the transcript.

Fixed

• Fixed /reload silently dropping the --tools / --exclude-tools filter: reload now preserves active tool loadout states through ToolLoadout.
• Fixed permission gate false positives: anchored dangerous system commands to command position and blanked non-shell quoted strings.
