Implemented a scheduler based on agenda and modified the Tool execute interface to adapt

[Disviel]

Closes #112 #113 #114 #115 #116 #117

This pull request introduces a new Agenda-backed job scheduling system to the EMA codebase, along with improvements to the chat UI and various supporting updates. The main changes include the addition of typed scheduler interfaces and job definitions, refactoring of the chat page to improve status handling and initialization, and enhancements to MongoDB connection handling. Below are the most important changes grouped by theme:

Scheduler System Integration

• Added a new Agenda-backed scheduler domain with typed interfaces, job specs, and handler signatures in src/scheduler/base.ts. This establishes a stable API for scheduling and managing jobs.
• Introduced job data definitions and handler mappings in src/scheduler/jobs/index.ts, including a demo job and handler in src/scheduler/jobs/test.job.ts. [1] [2]
• Created a central export for scheduler modules in src/scheduler/index.ts.

Chat UI Improvements

• Refactored the chat page (src/app/chat/page.tsx and page.module.css) to use a unified notice state for displaying status messages, improved initialization logic with caching, and updated UI styles for better feedback and accessibility. [1] [2] [3] [4] [5] [6] [7] [8] [9] [10]

MongoDB Enhancements

• Added getUri() methods to both in-memory and remote MongoDB classes to provide connection URIs, improving testability and integration with external tools. [1] [2] [3] [4] [5]

Actor and Agent Context Improvements

• Introduced ActorScope and passed contextual information through toolContext, enabling tools to access actor, user, and conversation IDs during execution. [1] [2] [3] [4] [5]

Dependency Updates

• Added new dependencies for Agenda scheduling (@hokify/agenda, mongodb-agenda) in package.json files for both ema and ema-ui packages. [1] [2] [3]

Pull request overview

Implements an Agenda-backed job scheduler in packages/ema (including server integration) and refactors the tool/skill execution interface to support structured args plus optional execution context.

Changes:

• Add AgendaScheduler with job handler registry, plus comprehensive scheduler tests.
• Introduce ToolContext / ActorScope and switch tool execution from positional args to {...args} payloads.
• Patch @hokify/agenda to work alongside MongoDB v7 by using an aliased MongoDB v4 dependency (mongodb-agenda).
