V0.8.0/dotnet benchmark

[gimlichael]

This pull request introduces the new dotnet-benchmark skill for .NET performance testing, extends the trunk-first-repo skill with a safer push-remote workflow, and strengthens git-keep-a-changelog with mandatory base-commit inspection for concrete releases. It also updates the documentation and installation instructions to reflect these new capabilities and improvements.

---

New Skill: dotnet-benchmark

• Introduces the dotnet-benchmark skill, providing a comprehensive BenchmarkDotNet-based benchmarking workflow for .NET types, including project scaffolding, parameter collection, runner infrastructure, onboarding documentation, eval coverage, and README showcase. [1] [2] [3]
• Adds FORMS.md, benchmark project templates, runner infrastructure, a requirements-checking script, and detailed reference docs for dotnet-benchmark.

Improvements to trunk-first-repo

• Adds a push-remote workflow mode that allows safe first-time remote pushes by sending main before feature branches, with explicit mode selection and improved guidance in both the README and SKILL.md. [1] [2] [3]
• README and documentation now clarify the branching logic depending on when origin is configured, and highlight the new safer first-push behavior. [1] [2]

Strengthening git-keep-a-changelog

• Enforces mandatory base-commit inspection for concrete releases, requiring explicit reporting of foundational version bumps and manifest changes before diff and commit analysis. Step 4 is now divided into clear sub-steps (4a–4f) with improved documentation and eval coverage.
• README and SKILL.md are updated to emphasize the critical importance of base-commit inclusion and the consequences of omission.

Documentation and Release Management

• Updates the CHANGELOG.md with detailed entries for versions 0.8.0, 0.7.5, and 0.7.4, and adds compare links for the new releases. [1] [2]
• README is updated to include installation instructions, feature descriptions, and "Why?" sections for the new and improved skills. [1] [2] [3] [4]

Greptile Summary

This PR introduces the dotnet-benchmark skill for evidence-driven BenchmarkDotNet performance testing, standardizes local PowerShell invocations to pwsh 7+ across all skill documentation and validation tooling, and extends trunk-first-repo with a guarded push-remote workflow. It also retroactively documents versions 0.7.4 and 0.7.5 in the CHANGELOG alongside the new 0.8.0 entry.

• dotnet-benchmark skill: Full skill package including SKILL.md, FORMS.md, two benchmark asset templates (comparison-benchmark.cs, operation-benchmark.cs), check-benchmark-requirements.ps1 detector, validate-skill.ps1 harness, six reference documents, and 12 evals covering discovery, semantic preflight, yolo mode, runner-skip preflight, and proportionate-stopping scenarios.
• pwsh standardization: A new Get-LocalShellPolicyFindings scanner was added to validate-skill-templates.ps1 to enforce pwsh in all local command examples; CONTRIBUTING.md, all skill SKILL.md files, and AGENTS.md were updated accordingly.
• trunk-first-repo push-remote workflow: Step 3a now routes late-remote cases through the guarded Push Remote Workflow (branch check + git ls-tree seed verification + main:main first).

Confidence Score: 5/5

Safe to merge. All previously flagged issues are resolved and the new dotnet-benchmark skill package is self-consistent.

The PR is a clean skill addition and standardization pass. The only finding is a missing [Unreleased] CHANGELOG placeholder, a process convenience concern that does not affect any shipped behavior.

CHANGELOG.md — no [Unreleased] section was added after closing out v0.8.0, so the next contributor will need to add one manually.

Important Files Changed

Filename	Overview
skills/dotnet-benchmark/SKILL.md	New skill with well-structured 10-step workflow, yolo-mode support, semantic preflight gates, runner-skip preflight, and proportionate-stopping guidance.
skills/dotnet-benchmark/scripts/validate-skill.ps1	Deterministic validator with pwsh 7+ harness-detector fixture test. Previously flagged issues (static class assertion, powershell invocation) are resolved.
scripts/validate-skill-templates.ps1	Adds Get-LocalShellPolicyFindings scanner with two patterns and self-test with 11 fixture cases. CHANGELOG.md and the script itself are correctly excluded from scanning.
CHANGELOG.md	Adds entries for v0.8.0, v0.7.5, and v0.7.4. The [Unreleased] section is removed without adding a new placeholder.
skills/trunk-first-repo/SKILL.md	Step 3a now correctly routes late-remote cases through the guarded Push Remote Workflow.
CONTRIBUTING.md	Updated validator invocation from powershell -NoProfile -ExecutionPolicy Bypass to pwsh -NoProfile with cross-platform path.
