Release NetDiagram-PS 1.4.0 (Gallery + tag) #76

Context

Gallery / manifest still 1.3.0; CHANGELOG [Unreleased] holds #55–#71 (and this cycle’s fixes). Cut 1.4.0 last after NetBox/SnmpWalk/cred-map/CI smoke land.

Tip: c47f0a1 (+ merge this cycle first).

What

1. Bump ModuleVersion to 1.4.0; refresh ReleaseNotes/Tags.
2. Move Unreleased bullets into [1.4.0] dated section; leave empty Unreleased.
3. Tag v1.4.0 on main after green CI.
4. Publish to PowerShell Gallery (Publish-Module) using existing release practice / secrets — do not paste Gallery key into chat/logs.

Acceptance criteria

• Manifest 1.4.0 matches CHANGELOG heading
• Tag v1.4.0 points at release commit on main
• Gallery shows NetDiagram-PS 1.4.0 (or publish job succeeds)
• CI green on release commit

Out of scope

MCP. Re-litigating #65–#71 content. LLDP mega-features.
