docs: new terminology for roadmap

Propose new Terminology for roadmap

I wasn't asked, but... as a new user of roadmap, it was very unobvious to me why "Milestone" is not a point in time, but rather a group of deliverables, so I came up with this proposal. I don't want to introduce yet another solution, instead I propose to follow common PM practices.

I've kept the changes straightforward. I think this is a good timing for such a change, as it will help to coordinate between components roadmaps and Logos Testnets.

Motivation

• Current terminology uses "Milestone" ambiguously for both work packages (weeks/months of effort) and zero-duration checkpoints (e.g., "rc.1")
• Testnets were incorrectly called "milestones" when they're actually versioned releases
• Inconsistent understanding of how work is structured and tracked

Changes

Key Terminology Updates

Old Term	New Term	Definition
Milestone (work container)	Initiative	Top-level work container spanning weeks/months with outcomes, resources, and risks
Testnet vX	Release	Timeboxed bundle shipped for testing or external use
N/A	Milestone (checkpoint)	Zero-duration gate inside a release (e.g., "RC freeze", "go-live")

Initiative fields:

• Monitoring Links

• Gradual adoption in new initiatives/releases
• Prepare an Initiative template
