Add CI tests, Windows installer cleanup, and streaming click-track rendering

[eimexdev]

Summary

• Added a CI test job before installer packaging and expanded local build docs to reflect release packaging behavior.
• Improved analysis cache handling with Windows-native cache paths and versioned cache keys.
• Switched click-track generation to streaming block writes to reduce peak memory usage.
• Hardened subtitle timeline import so Resolve track state is restored even on append failure.
• Updated tests to cover Windows cache paths, cache invalidation inputs, streaming render stability, and installer packaging flags.

Testing

• Passed python3 -m compileall openbeat scripts tests.
• Passed Lua syntax loading for OpenBeatCommon.lua.
• Passed the test suite with uv run --no-project --python 3.11 --with-editable . python -m unittest discover -s tests -v.
• Branch has been updated against current main; CI is rerunning under the artifact-upload-safe workflow.

📝 Walkthrough

Walkthrough

Adds platform-aware analysis caching and sample-rate-aware cache keys, streams click-track rendering in blocks, makes PyInstaller builds platform-specific with Windows GUI/install metadata improvements, updates CI to run tests before builds, and revises docs for platform-specific build and log locations.

Changes

Platform-specific installers and audio infrastructure

Layer / File(s)	Summary
Platform-aware analysis and versioned caching openbeat/analysis.py	Introduces ANALYSIS_TARGET_SR and CACHE_SCHEMA_VERSION, adds sys_platform(), makes default_cache_dir platform-aware, and makes cache keys/paths include target_sr and versions.
Memory-efficient block-based click track rendering openbeat/artifacts.py	Refactors render_click_track to stream PCM in configurable block_size blocks, precompute click starts, maintain active clicks per block, and write per-block via soundfile.SoundFile.
Platform-specific CLI binary building configuration scripts/build_installers.py	Generalizes pyinstaller_binary with onefile/windowed flags and stale-output cleanup; updates build_cli_binary(platform=...) and separates macOS/Windows builds in main orchestration.
Windows installer GUI and post-install workflow scripts/build_installers.py	Refactors embedded Windows installer payload handling, adds helpers (Resolve detection, log path, open_path), makes install_openbeat return installed-path metadata, and enhances Ready/Finish wizard steps with install summary and post-install actions.
Error handling for DaVinci Resolve timeline operations resolve/Fusion/Modules/OpenBeat/OpenBeatCommon.lua	Wraps AppendToTimeline in pcall, captures append result, restores track states unconditionally, and returns errors from failed append calls.
Test coverage for analysis, rendering, and build system tests/test_analysis.py, tests/test_build_installers.py	Adds tests for block-size rendering consistency, Windows default_cache_dir, cache key sensitivity to version/target_sr, and Windows PyInstaller flag selection.
CI/CD integration and user documentation .github/workflows/build-installers.yml, docs/development.md, docs/guide.md	Adds a jobs.test that runs before installer builds, updates development docs to use platform-specific build commands, and separates macOS/Windows log paths in the guide.

In blocks I tap the metronome's cheer,
keys now mark versions, platforms clear,
installers bundle where they belong,
Windows shows paths and buttons strong.

Remove windowed mode from Windows CLI runtime build

Building the bundled openbeat runtime with --windowed makes it a noconsole app on Windows, where PyInstaller documents that sys.stdout/sys.stderr are unavailable; this conflicts with the shipped CLI implementation (for example click-track prints JSON in openbeat/cli.py) and can raise runtime errors instead of producing output. In the installer flow, Resolve invokes this binary for click-track generation, so Windows installs can fail during normal feature use even though packaging succeeds.
