Runner images have migrated from /usr/share/rust/.cargo/bin to standard
~/.cargo/bin location. Action now checks old location first and migrates
binaries if found, maintaining compatibility with both paths.
Bump cache key to v3 to ensure fresh binary cache after path changes.
Matrix jobs stopped starting after upgrading from runner v9 to v11 due to
changes in job dependency resolution. Remove redundant define-variables job
that computed static image paths and replace with IMAGE_PATH environment
variable.
Also fix timelord action binary caching for compatibility between different
runner images that install cargo binaries in different locations.
Enable automatic merging of ghcr.io/renovatebot/renovate docker image updates
to reduce manual maintenance overhead.
Reorganise package rules by manager type (cargo, github-actions, docker) and
add missing description for cargo concurrency limit rule to improve config
maintainability.
Separate fast release builds from slow max-perf builds to optimise runner
utilisation and provide quicker feedback. Release builds complete first with
standard optimisations, followed by Haswell-optimised dragrace builds once
the safe builds pass successfully.
Extract build logic into focused composite actions for better log visibility
in Forgejo UI. Split monolithic build action into prepare-docker-build,
inline docker build step, and upload-docker-artifacts to ensure each phase
completes independently and shows logs immediately.
Creates separate manifests at each stage to avoid waiting for all builds
before publishing.
The workflow was rebuilding dependencies unnecessarily despite timelord
restoring timestamps because TARGET_CPU and RUST_PROFILE weren't passed
to Docker, creating inconsistent cache keys. Now passes both arguments
for proper cache reuse.
Adds Haswell-optimised builds alongside baseline builds using -march=haswell
for PCLMUL instruction support. Recent build improvements reducing compile
times from 15-20 minutes to ~5 minutes make this additional CPU variant
feasible. Users can pull optimised images with -haswell suffix.
