Add design documentation and per-concept requirements files for review sets

[Copilot]

ReviewMark review sets lacked requirements and design documentation, making reviews incomplete. This adds docs/reqstream/ (split requirements YAML) and docs/design/ (design markdown) so each review set contains requirements, design, code, and tests — following the VersionMark pattern. Also adds ValidationTests.cs to provide unit test coverage for the Validation class.

Description

docs/reqstream/ — Per-concept requirements (split from monolithic requirements.yaml)

• command-line.yaml — SarifMark-Cli-*
• sarif.yaml — SarifMark-Sarif-*
• report.yaml — SarifMark-Rpt-*
• validation.yaml — SarifMark-Val-*, SarifMark-Enf-*
• platform.yaml — SarifMark-Plt-* (includes source filter prefix documentation)
• ots-software.yaml — SarifMark-OTS-*

docs/design/ — Design documentation with inline requirement traceability

• introduction.md — scope, audience, relationship to requirements and code
• command-line.md — Program.cs dispatch table, Context.cs property table, argument parser
• sarif.md — SarifResult / SarifResults reading pipeline, version extraction, ToMarkdown generation
• utilities.md — PathHelpers.SafePathCombine defence-in-depth validation
• validation.md — three self-validation tests, WriteResultsFile format dispatch, TemporaryDirectory
• title.txt, definition.yaml — Pandoc document generation support

requirements.yaml — Refactored to includes: pattern

Source filter prefix documentation moved to docs/reqstream/platform.yaml where it is co-located with the platform requirements that use it.

includes:
  - docs/reqstream/command-line.yaml
  - docs/reqstream/sarif.yaml
  - docs/reqstream/report.yaml
  - docs/reqstream/validation.yaml
  - docs/reqstream/platform.yaml
  - docs/reqstream/ots-software.yaml

.reviewmark.yaml — Restructured from 3 → 5 focused review sets

Each set now lists its reqstream YAML and design markdown alongside source and tests:

Review Set	Reqstream	Design	Tests
SarifMark-CLI-Review	command-line.yaml	command-line.md	ProgramTests.cs, ContextTests.cs
SarifMark-SARIF-Review	sarif.yaml, report.yaml	sarif.md	SarifResultsTests.cs
SarifMark-Validation-Review	validation.yaml	validation.md	ValidationTests.cs
SarifMark-Utilities-Review	—	utilities.md	PathHelpersTests.cs
SarifMark-Integration-Review	platform.yaml, ots-software.yaml	—	IntegrationTests.cs

test/DemaConsulting.SarifMark.Tests/ValidationTests.cs — New unit tests for Validation

6 unit tests covering Validation.Run:

• Null context throws ArgumentNullException
• Valid context prints validation header (version, machine name rows)
• Valid context runs all three tests and reports them as passed
• Valid context prints summary with correct totals (3 total, 3 passed, 0 failed)
• TRX results file is written when --results .trx is supplied
• JUnit XML results file is written when --results .xml is supplied

Each test disposes the context before reading the log file, ensuring correct behaviour on Windows where file handles are exclusive.

<issue_title>[Feature]: Design and Requirements Review Sets</issue_title>
<issue_description>### Problem Statement

The ReviewMark review-sets for this project need requirement and design documentation files.

Proposed Solution

The https://github.com/demaconsulting/VersionMark repository demonstrates the approach to organizing the requirements and design documentation:

• The docs/reqstream folder contains the requirements yaml files split into concepts aligning with the review sets
• The docs/design folder contains a design document (pandoc + title + markdown files) for the design documentation - with files separated by concepts compatible with the review sets
• The review-sets of .reviewmark.yaml all contain requirements, design, code, and tests

This approach aligns with https://github.com/demaconsulting/ContinuousCompliance/blob/copilot/expand-reviewmark-assistance-ai/docs/file-reviews.md

The root cause was using var context keeping the log file writer open when File.ReadAllText was called — Windows enforces exclusive file access, Linux/macOS don't. Fixed by replacing using var context with a scoped using (...) block so the context (and its log writer) is disposed before reading the file. Applied to all five tests that read the log after Validation.Run. (commit 5098ed7)
