dcr Files

Added:

• OpenBSD and NetBSD target support — full platform routing with dynamically generated target triples using std::env::consts::ARCH and std::env::consts::OS. Affects build, run, clean, and the platform module.
• src/platform/bsd.rs — new dedicated BSD platform module shared by FreeBSD, OpenBSD, NetBSD, providing bin_path, lib_path, elf_path, efi_path, and shared_lib_path.
• build.out_dir configuration option — custom output directory that overrides the default target/<triple>/<profile> path for final artifacts. Supported in build, run, and config validation.
• dcr fmt command — new CLI command that formats all C/C++ source files (*.c, *.cpp, *.h, *.hpp) in src/ and tests/ using clang-format.
• Incremental linking — needs_link() function in common.rs that checks whether any object file is newer than the linked output, skipping unnecessary re-linking. Implemented for all backends (unix_cc, msvc, gas, nasm).
• build.kind = "none" and "custom" — two new project kind types for special build scenarios where no standard artifact is produced.
• install_bsd.sh — dedicated POSIX-compliant install script for BSD systems (FreeBSD, OpenBSD, NetBSD) with binary download and source build modes.
• Linux ARM64 support in install.sh — added Linux:aarch64|Linux:arm64 target triple detection for pre-built binary downloads.
• BSD OS detection in install.sh — FreeBSD, OpenBSD, NetBSD detection and target triple resolution.
• rust-toolchain.toml — explicit stable channel toolchain pinning.
• Nix support — flake.nix for Nix package manager. Run via nix run github:dexoron/dcr or install with nix profile install github:dexoron/dcr. Contributed by community contributor.
• Snapcraft publish — dcrup published on Snapcraft. Install with sudo snap install dcrup.
• Integration tests — build_with_target_config (verifies build.target = "linux") and build_with_out_dir (verifies custom output directory).
• get_build_string_with_profile made pub — so run.rs can resolve custom output directory configuration.

Changed:

• build.target semantics changed — now strictly holds the target triple (e.g. x86_64-unknown-linux-gnu) or a short name (linux, macos, windows). No longer doubles as a custom output directory — that functionality moved to build.out_dir.
• build.standard made optional — changed from String to Option<String>. Validation only enforces non-empty for non-ASM languages. Skipped in dcr.toml output when empty.
• dcr run with out_dir — now resolves target directory respecting build.out_dir when configured, via get_build_string_with_profile() from build.rs.
• collect_sources() returns empty vec instead of error when no source files are found, allowing kind = "none" or kind = "custom" projects to have no source files.
• CI/CD release workflow refactored — git2 made target-specific (no vendored-openssl on Windows), Zig-based cross-compilation for non-x86_64 Linux targets, Arch Linux package version sanitization (dashes → dots), NetBSD gmake symlink.
• README compatibility table — FreeBSD, OpenBSD, NetBSD build/runtime status upgraded from community/best-effort to officially supported.
• Documentation rewritten — available at dcr.dexoron.su/docs or in the docs/ directory. Installation guides, commands, and reference updated to reflect current CLI and config format.
• Site rewritten — dcr-site migrated to Docusaurus with internationalization (i18n) support, improved navigation, and updated content across all sections.
• Dev channel dependency check in install.sh — checks for python3 or jq before attempting dev channel installations.

Fixed:

• dcr run stdout/stderr not inherited — child process output was captured and manually printed, breaking interactive programs. Fixed by switching to Command::status().
• Release CI race condition — build matrix jobs could upload assets to a release that did not yet exist. Fixed by adding a dedicated create-release job.
• GHA release — stable toolchain override — resolved Rust toolchain override issues in CI.
• Arch Linux package version sanitization — version strings with dashes (e.g. 0.7.0-dev) are invalid for Arch Linux pkgver. Fixed by replacing dashes with dots.
• GPG permissions after Docker — Docker operations changed GPG directory ownership. Fixed by running chown after Docker commands.
• RPM package artifact paths — RPM artifacts placed under rpm/x86_64/ instead of fedora/x86_64/. Corrected in Dexoron Packages Index workflow.
• install.sh JSON parsing robustness — added jq as primary parser with python3 fallback for dev channel release lookups.

Removed:

• format_roots() helper — removed from common.rs. Was only used by the old error path in collect_sources().
• Individual per-distro artifact download steps — three separate actions/download-artifact steps replaced with unified gh release download --clobber.
