Implement CI/CD workflows for MonocleForDynamo (modeled after Rhythm)

[Copilot]

MonocleForDynamo had no automated build or release pipeline. This adds GitHub Actions CI/CD patterned after RhythmForDynamo.

Changes

.github/workflows/build.yml

• Triggers on push/PR to main/master and workflow_dispatch
• Builds all 18 Dynamo release configurations (Release 2.0 → Release 3.4) via MSBuild on windows-latest
• Verifies deploy/ folder contains all expected MonocleViewExtension.dll artifacts post-build
• Commits updated deploy/ back to branch on push events ([skip ci] to prevent loop)
• Uploads deploy/ as a GitHub artifact (30-day retention)

.github/workflows/release.yml

• Triggers on workflow_dispatch (optional manual minor version) or tag push matching 20*.*.*
• Auto-calculates CalVer (YEAR.MONTH.MINOR) by scanning existing tags, with numeric-safe comparison to handle non-numeric suffixes
• Creates a GitHub release via softprops/action-gh-release

src/Monocle/Monocle.csproj

• Replaced hardcoded local developer path for FolderPackages with an MSBuildProjectDirectory-relative path so the post-build DLL copy works in CI without any property overrides:

<!-- Before -->
<FolderPackages>C:\Users\piersoj\Documents\Repos\MonocleForDynamo\deploy\$(BuildOutput)\</FolderPackages>

<!-- After -->
<FolderPackages>$(MSBuildProjectDirectory)\..\..\deploy\$(BuildOutput)\</FolderPackages>
