docs: document Windows test prerequisites

[redzwanmutalib]

Summary

• document native Windows test-suite limitations
• explain Developer Mode/elevated-shell symlink requirements and Windows long-path policy
• recommend WSL/Linux for exact Ubuntu CI parity
• clarify that Pyright is currently a local advisory check, not a blocking CI job

Verification

• uv run --frozen ruff check .
• all five tools.skillgen consistency guards
• git diff --check

Scope

Documentation-only: README.md. No source, test, generated artifact, hook, skill, or system-setting changes.

Graphify reviewed this change.

Looks safe to merge — no coupling regressions and no blocking issues, checked against the code graph (not a self-assessment).

Graphify review — findings

This pull request adds a new "Windows note" callout to the README's testing section. The note documents Windows-specific test suite considerations, such as enabling Developer Mode for symbolic links, the LongPathsEnabled policy, and clarifies that CI runs on Ubuntu with Python 3.10/3.12 while Pyright is a non-blocking advisory check. The change is documentation-only.

No blocking issues surfaced.

Analysis details — impact, health, verification

Impact & health

Graphify review

Impact — 25 functions depend on the 25 functions this change touches.

Health — grade A; no new coupling hotspots.

Verification — 25 functions in the blast radius were not formally verified this run (proofs are advisory here).

Gate & verification

graphify gate

PASS — objectively clean (no health regressions, tests not run — proofs not run this pass (advisory)). Grounded, not self-assessed.

Advisory (not blocking):

• verification_scope: 25 function(s) in the blast radius were not formally verified this run
