feat: Add Mikado Method semantic anchor

[Copilot]

Adds the Mikado Method (Ellnestam & Brolund, 2012) as a new semantic anchor — a graph-based refactoring technique for safely navigating large changes in legacy codebases via prerequisite discovery and leaf-first resolution.

New files

• docs/anchors/mikado-method.adoc — English anchor: core concepts (Mikado Goal, prerequisite discovery, revert-and-repeat cycle, Mikado Graph, leaf-first resolution), roles, related anchors
• docs/anchors/mikado-method.de.adoc — German translation

Updated files

• website/public/data/anchors.json — new entry under development-workflow category; roles: software-developer, software-architect, team-lead; related: tdd-chicago-school, tdd-london-school
• skill/semantic-anchor-translator/references/catalog.md — entry added to the Development Workflow section

<issue_title>[Anchor Proposal]: Mikado Method by Ola Ellnestam and Daniel Brolund</issue_title>
<issue_description>### Proposed Term

Mikado Method

Context (Optional)

The Mikado Method is a refactoring method for large code bases. It was proposed by Ola Ellnestam and Daniel Brolund in their book "The Mikado Method" first published 2009. The method is inspired by the game Mikado and describe a process to do larger changes by small, reversible steps without breaking the whole system. The result is a graph of pre-conditions to be met before the final refactoring can be done.

Pre-submission Checklist

• I have searched existing anchors and this term is not already included
• This term refers to a well-established concept (not something I invented)</issue_description>

@rdmueller Sorry for the delay. I am not sure how carefully I should check but this looks good to me. I would add that the attempt to make small changes should also be time boxed. If it takes too long, the change is not small enough.

Thanx!
