- `build.kind = "efi"` — UEFI PE32+ executable support. Links with `-shared -nostdlib -Wl,-dll -Wl,--subsystem,10`, output via `efi_path()` with `.efi` extension, rejected by `dcr run`.
- `build.kind = "elf"` — bare-metal ELF executable support. Uses `elf_path()` output path, rejected by `dcr run`, no extra linker flags.

Fixed:

- `dcr run` with `--target` or `build.target` now correctly finds the binary in the arch-specific target directory.
- `dcr run` checks profile-specific `build.{profile}.kind` before rejecting library builds (previously only checked `build.kind`).
- `dcr clean` now reads `build.target` from `dcr.toml` when no `--target` flag is given.
- Linux: target directory is now consistent — `target/<arch>-unknown-linux-gnu/<profile>/` (no stale `target/<profile>/`).
- `dcr.lock` is now populated with all resolved dependencies (registry, path, git) instead of being always empty.
- Git dependencies are now properly recognized and recorded in `dcr.lock`.
- `is_registry_dep` correctly identifies version-based registry dependency tables (`{ version = "..." }`) and rejects tables with unknown keys.
- `dcr test` accepts `--debug`/`--release` flags (defaults to `debug` profile instead of always `release`).
- Build fingerprint cache (`build_cache_path`) now includes `target_dir` — different targets no longer share a single cache entry.
- `object_path` no longer hardcodes the `src/` prefix — works correctly with custom `build.roots` (e.g. `roots = ["lib"]`).
- `dcr update` now generates `.exe` candidates for all Windows targets, not just `x86_64-pc-windows-msvc`.
- Compiler existence is verified before starting the build (clear error if compiler is not found in PATH).
- Consolidated duplicate `OUTPUT_MUTEX` definitions — MSVC backend now uses the shared mutex from `common.rs`.
- Registry cache root directory is created if missing (prevents cryptic errors when `~/.dcr/` does not exist).

- Incremental rebuild checks source/object mtime and tracked header dependencies.
- `--force` skips build cache checks and recompiles.
- `--clean` removes `target/<profile>` and `build.clean` paths before building.

- `build.filename` + `build.extension` allow full control over the final artifact name (e.g. `KERNEL.BIN` instead of using `package.name`). When `build.kind = "efi"`, the output is a PE32+ executable with `.efi` extension.
- `build.kind = "efi"` links with `-shared -nostdlib -Wl,-dll -Wl,--subsystem,10` for UEFI PE32+ format. Use `build.filename` and `build.extension` for full control over the artifact name.
- `build.kind = "elf"` produces a bare-metal ELF executable. Linking flags are user-controlled via `build.ldflags` (no PIE/CRT defaults are added).
- Default GCC/Clang profile flags: `debug` -> `-O0 -g -Wall -Wextra -fno-omit-frame-pointer -DDCR_DEBUG`, `release` -> `-O3 -DNDEBUG`.
These defaults are **not applied** for bare-metal targets (e.g. `aarch64-none-elf`, targets containing `none` / `-elf` / `eabi`).
- For `language = "asm"` with `compiler = "as"`/`"gas"`, use `.s` files (no preprocessing). For `.S`, use `gcc` or `clang`.

## Behavior
- Without arguments: removes entire `target/`.
- With profile: removes only `target/<profile>/`.
- With profile: removes only the profile-specific directory. Respects `build.target` from config: if `build.target = "aarch64-unknown-linux-gnu"`, cleans `target/aarch64-unknown-linux-gnu/<profile>/`.
- With `--all`: also cleans all workspace members.
- Additionally removes paths from `build.clean` if configured.
- `build.clean` supports `{profile}` and version placeholders.

## Restrictions
- If `build.kind = "staticlib"` or `build.kind = "sharedlib"`, `run` exits with error.
- If `build.kind` (or `build.{profile}.kind`) is `"staticlib"` or `"sharedlib"`, `run` exits with error.
- The profile is selected from the first argument.
- `--target <triple>` runs the binary for specified target (short names: `linux`, `macos`, `windows`).
- `--force` skips build cache checks and recompiles.

@@ -39,6 +40,6 @@ DCR uses a simple test framework:
- Test binary is linked with the main project (for lib projects) or standalone.
- `--init` creates `tests/dcr_test.h` and `tests/test.c` if missing.
- Tests run in release mode by default for performance.
- Tests run in debug mode by default. Use `--release` for release mode.
- Custom test logic can be added by editing `tests/test.c`.
- Fails if no `tests/test.c` exists (run `dcr test --init` first).
