Come up with more user-friendly scheme for random workspace names

MR:

• Generate a user-friendly name for workspaces (!202750 - merged) • Ashvin Sharma • 18.4
• Optimize workspace names length (!204625 - merged) • Ashvin Sharma • 18.5

Problem Statement

Currently, workspaces use basic random alphanumeric strings for naming which are not user-friendly or memorable. This makes it difficult for users to:

• Identify their workspaces at a glance
• Debug issues when multiple workspaces exist

Proposed Solution

Implement a naming scheme using combinations of adjectives and nouns (e.g., clever-einstein, happy-penguin, focused-curie) similar to how Docker generates container names.

Acceptance Criteria

• Replace SecureRandom.alphanumeric with adjective-noun combination generator
• Ensure global uniqueness with collision detection and retry mechanism
• Add following keys in the annotations
  • workspaces.gitlab.com/agentk_id
  • workspaces.gitlab.com/project_id - this will be optional if we add project-less workspaces
  • workspaces.gitlab.com/namespace_id - this is the GitLab group AKA namespace - we don't call it group_id because in the future we may support also personal namespaces. For now, this would be the id of the group containing the project.

Benefits

1. User Experience: Memorable, human-readable workspace names
2. Debugging: Easier to identify and reference specific workspaces
3. Communication: Teams can easily discuss workspaces by name when we have shared workspaces
