Plugin Qualifier Parameters

Plugin qualifiers now receive with-clause parameters from ARO statements. This lets qualifiers accept configuration at the call site:

Compute the <result: collections.pick-random> from the <items> with <count>.

The with-clause value is passed through to the plugin's qualifier function alongside the input, and plugins are now loaded and testable in the test harness.

REPL: /plugin add

Install and load plugins directly from a Git repository inside the REPL:

aro> /plugin add https://github.com/arolang/plugin-swift-hello.git

The plugin is cloned, built, and registered in the current session.

Unified Plugin Host Architecture

The three separate plugin host implementations (Native, Python, Swift) now share a common PluginHostProtocol abstraction, reducing ~400 lines of duplicated loading, caching, and lifecycle code. No user-visible behaviour changes.

Security & Stability Fixes

• Python plugin code injection — plugin subprocess communication now uses length-prefixed binary framing instead of evaluating raw strings; subprocess timeouts prevent hung plugins from blocking the runtime
• C interop memory leaks — fixed missing aro_plugin_free() calls after aro_plugin_info and aro_plugin_execute in the native plugin host
• Parser — template added to known external identifiers, fixing false "unknown identifier" warnings in template-heavy applications

Housekeeping

• Removed unused ComputeAction.normalizeFieldName, dead RuntimeBridgeProtocol, and deprecated legacy initializer
• Updated website packages and writing-extensions pages to match current codebase
