Lexora Buddy: vanhemmat versiot ja versiohistoria

This update improves handoffs and continuation in multi-agent workflows. Companions can build on previous context and results to refine or rework an assignment, share relevant materials, and communicate directly with one another, reducing repeated explanations. Execution details now distinguish task requirements, delivery evidence, and review outcomes.
It also fixes issues with companion identity, coordination waits, and task completion feedback, while improving @mention routing and independent scheduling, access to previous reports, result actions, and usage display.

This release focuses on Lexora Office and document workflows. Alongside the Office plugin, we added file-opening preferences, content references, bundled skills, clipboard access, and private document storage—connecting document editing, conversations, and AI-generated deliverables so companions can work with documents rather than only discuss them.
This version also introduces a Windows ZIP distribution, customizable companion stickers and notification sounds, plus improvements to reading position, companion collaboration, and the built-in browser.
