Fix stale README note about bundled .neo/skills examples

[owainlewis]

Summary

Fix the README Skills section, which says this repository ships $review and $commit examples under .neo/skills/, even though that directory is not present.

Evidence

• README.md says this repo ships $review and $commit under .neo/skills/.
• rg --files -g "SKILL.md" -g ".neo/**" finds no checked-in .neo/skills examples in this repository.
• The Skills section is otherwise useful and should stay focused on the supported file layout.

Acceptance criteria

• README no longer claims bundled .neo/skills examples that are not present.
• The Skills section still explains project and global skill locations.
• If examples are mentioned, they accurately reflect files that exist in the repo.

Agent Assessment

Risk: low
Type: docs
Agent-ready: yes

Reason:
This is a small documentation correction with an easy file-existence check and no behavior changes.

Suggested plan:

1. Remove or rewrite the stale sentence about bundled $review and $commit examples.
2. Keep the general skill usage documentation intact.
3. Verify with rg --files -g "SKILL.md" -g ".neo/**".

Agent Assessment

Risk: low
Type: docs
Agent-ready: no

Reason:
The core evidence in this issue is now stale and contradicted by the repository. The issue states that the README claims bundled $review/$commit examples under .neo/skills/ even though that directory is not present. In the current tree both .neo/skills/review/SKILL.md and .neo/skills/commit/SKILL.md are checked in (added by merged PR #74, "feat: skill loading with $name expansion"), and README.md lines 204-206 accurately describe them as working examples. Acting on this issue as written would delete a correct statement.

Evidence:

• git ls-files lists .neo/skills/review/SKILL.md and .neo/skills/commit/SKILL.md.
• README.md:204-206: "This repo ships $review and $commit under .neo/skills/ as working examples."
• Merged PR feat: skill loading with $name expansion (closes #62) #74 shipped these example skills.

Human needed:
The premise appears invalid. Please confirm whether this issue should be closed as no longer applicable, or rescoped to a real, still-present README inaccuracy. Routed to needs:human and agent:ready removed so an unattended agent does not delete accurate documentation.
