v0.1.0 - Initial public release

DMD Performance Prototype: Initial Public Release

This release publishes the first public version of the DMD performance
prototype.

The project is a D-first benchmarking and regression-analysis toolkit for DMD.
It is designed to measure release-to-release compile-time behavior, capture
compiler phase costs with -ftime-trace, run focused experiments, and
generate review-ready evidence such as CSV summaries, charts, and reports.

Highlights

• Added a dual-track benchmarking workflow:
  • latest20 for the most recent DMD releases
  • compatible20 for stable host-compatible regression analysis
• Added D-native CLI support through dmdbench
• Added Python and shell-based analysis/reporting workflows
• Added verification summaries, chart indexes, and generated performance
  charts
• Added release-cache bootstrap support for more reproducible runs
• Improved Linux gap-close CI and permissions handling
• Expanded repository documentation with workflow and architecture diagrams

What this repo helps with

• Benchmarking DMD compiler performance across releases
• Finding compile-time regressions
• Attributing cost by compiler phase using -ftime-trace
• Running targeted experiments for parser behavior, switch scaling, and
  related performance investigations
• Producing evidence that is easier to review and share

Current status

This is an early prototype and should be treated as an experimental toolkit
rather than a finalized product. Interfaces, workflows, and generated outputs
may continue to change as the benchmarking process is refined.
