feat: Add comprehensive package.json manifests at all plugin levels
...
Complete manifest hierarchy for plugin discovery:
- Root level: lists all 6 languages (python, go, rust, cpp, mojo, ts)
- Language level: lists all categories per language
- Category level: lists all plugins with metadata
Structure enables programmatic plugin discovery and loading
across the multi-language workflow plugin ecosystem.

refactor: Restructure multi-language workflow plugins to match Python pattern
...
Each plugin now follows the standardized structure:
- category/plugin_name/plugin_name.{ext} - Implementation
- category/plugin_name/package.json - Plugin metadata
- category/package.json - Category manifest with "plugins" array
Languages restructured:
- Go: 31 plugins across 7 categories (math, string, logic, list, dict, var, convert)
- Rust: 55 plugins as individual crates in Cargo workspace
- C++: 34 header-only plugins with complete coverage
- Mojo: 11 plugins across 3 categories (math, string, list)

feat: Propagate workflow plugins to Go, Rust, C++, and Mojo
...
Multi-language workflow plugin system following Python's structure:
- Each plugin in its own directory with implementation + package.json
- Category-level package.json manifests listing all plugins
- Consistent interface: run(runtime, inputs) -> outputs
Languages added:
- Go: math, string, logic, list, dict, var, convert (25+ plugins)
- Rust: math, string, logic, list, convert, var (50+ functions)
- C++: header-only math, string, logic, var, convert (30+ plugins)
- Mojo: math, string, list with systems programming features
Python structure fixed:
- Reorganized flat files into plugin subdirectories
- Added package.json metadata to all 120+ plugins
- Added missing backend category (15 plugins)
- Category manifests with plugin lists

refactor: Move core engine into executor/ts
...
The TypeScript core engine now lives inside executor/ts/ alongside the
TypeScript runtime, creating a cleaner structure where each executor
folder is self-contained.
Structure:
executor/ts/ # TypeScript runtime + core engine
├── executor/ # DAG executor
├── registry/ # Plugin registry
├── utils/ # Priority queue, template engine
├── types.ts # Type definitions
└── index.ts # Main exports
executor/python/ # Python runtime
executor/cpp/ # C++ runtime (Phase 3)

feat: Add Python plugins from AutoMetabuilder + restructure workflow folder
...
Restructure workflow/ for multi-language plugin support:
- Rename src/ to core/ (engine code: DAG executor, registry, types)
- Create executor/{cpp,python,ts}/ for language-specific runtimes
- Consolidate plugins to plugins/{ts,python}/ by language then category
Add 80+ Python plugins from AutoMetabuilder in 14 categories:
- control: bot control, switch logic, state management
- convert: type conversions (json, boolean, dict, list, number, string)
- core: AI requests, context management, tool calls
- dict: dictionary operations (get, set, keys, values, merge)
- list: list operations (concat, find, sort, slice, filter)
- logic: boolean logic (and, or, xor, equals, comparisons)
- math: arithmetic operations (add, subtract, multiply, power, etc.)
- string: string manipulation (concat, split, replace, format)
- notifications: Slack, Discord integrations
- test: assertion helpers and test suite runner
- tools: file operations, git, docker, testing utilities
- utils: filtering, mapping, reducing, condition branching
- var: variable store operations (get, set, delete, exists)
- web: Flask server, environment variables, JSON handling
Add language executor runtimes:
- TypeScript: direct import execution (default, fast startup)
- Python: child process with JSON stdin/stdout communication
- C++: placeholder for native FFI bindings (Phase 3)
