feat: portability, correctness, and quality improvements for v0.2
...
Portability (Linux distro-agnostic):
- Remove hardcoded Clang compiler enforcement; GCC now builds
- Add find_package(Threads REQUIRED) for older glibc
- Add cmake install() target
- FHS 3.0 default root: /kappa -> /usr/local/kappa
- fs::path operator/ for all init/bootloader paths (fixes prefix fragility)
- Multi-distro zoneinfo search (FHS, NixOS, Guix, alt)
- Portable tar extraction (drop GNU-only --no-same-permissions)
- Runit enable/disable commands now prefix-aware
- --root CLI flag before/after subcommand, lazy directory creation
- Shebang constants de-duplicated to types.hpp
Correctness (race conditions, UB, corruption):
- Fix CWD race in scheduler: per-child chdir() instead of process-global
- Fix UB const_cast in exec_cmd/exec_capture: mutable argv buffers
- Fix non-atomic installed DB writes: tmp+rename pattern
- Fix read_file() no longer calls exit(1), throws instead
- Fix silent catch(...) parse errors now print diagnostics
- Fix rebuild false positives with config_hash change detection
- Fix s6 disable_cmd copy-paste bug (was identical to enable)
- Fix runit enable_cmd incomplete, disable_cmd wrong target
- Fix dinit env vars: functional env-file + companion .env
Quality:
- Add -Wall -Wextra -Wpedantic to CMake, fix 2 pre-existing warnings
- Move parse_int from error.hpp to parse_util.hpp
- Fix hash verification guard checks all three hash types
- Check patch return code in fetch.cpp
- Add explicit system_dir creation in ensure_directories()
- Add resolve to needs_dirs for build_registry() consistency
- Update stale /kappa path references in examples
- Remove inaccurate -Werror claim in CONTRIBUTING.md
- Add build-gcc/ and agent dirs to .gitignore
- Suppress clang-tidy portability-avoid-pragma-once
- Fix .gitignore /kappa pattern (was matching include/kappa/)
- Delete stale vcpkg_installed/ directory
54/54 tests pass. Builds on Clang and GCC with 0 warnings.

feat: system-agnostic package manager — 5 inits, 2 bootloaders, parallel scheduler
...
Complete rewrite of kappa from a sequential build tool into a
system-agnostic package manager with runtime init switching.
Core additions:
- 5 init system backends: systemd, openrc, s6, runit, dinit
(service file generation, enable/disable, init_paths)
- 2 bootloader backends: grub, limine (config generation, fallback entries)
- Parallel scheduler with worker pool, depth-based priority (Beta/Alpha/Zeta),
atomic claiming, dependency tracking, deduplication, and failure propagation
- Init-switch impact analysis: only rebuild packages using ${enabledinit}
- Init-agnostic service definitions: flat NamedService blocks replace
per-init nesting
- Package conflicts: mutual incompatibility detection in resolver
- System groups: init-agnostic group creation in DSL
- Init-agnostic hostname/timezone: direct /etc/hostname and /etc/localtime writes
- Source tarball caching at /kappa/cache/ with atomic write-then-rename
- Package recipe caching with remote fetching and version comparison
- remotes = [...] block in system config for package repositories
- Auto-fetch: rebuild resolves missing packages from remotes
- uninstall phase in package definitions
- ${enabledinit} eval variable for init-conditional builds
- Shared util module (to_lower, shell_escape)
- 54 integration tests across two shell test suites
- Comprehensive README and CONTRIBUTING guide
Bug fixes from review:
- CRITICAL: Replace std::system() with fork+execvp (command injection)
- CRITICAL: Fix scheduler deadlock on successful completion
- CRITICAL: Fix rebuild init/kernel/bootloader change detection
- HIGH: Fix path traversal via unsanitized package names in cache
- HIGH: Fix TOCTOU race in cache write with atomic rename
- HIGH: Fix formatter dropping remotes/imports blocks
- HIGH: Fix formatter stripping empty-string assert values
- HIGH: Fix formatter non-idempotent output (sorted key iteration)
- HIGH: Populate ${enabledinit} from boot.init in BuildStep
- MEDIUM: Fix data race on non-atomic scheduler stop flag
- MEDIUM: Fix compute_depths() traversal direction
- MEDIUM: Add runit to doctor supported-init warning
- MEDIUM: Extract to_lower/shell_escape to shared kappa::util
- MEDIUM: Consolidate generator declarations in headers

fix: CWD restore, install error checks, fetch EINTR
...
- build.cpp: save/restore CWD on both success and failure paths
- install.cpp: check error_code after each filesystem op, abort on failure
- install.cpp: check write_installed() return value
- fetch.cpp: EINTR retry loop on both waitpid calls (exec_cmd + exec_capture)

fix: Phase 3+4 review — deterministic hash, EINTR, env restore, installer wiring
...
- std::hash→FNV-1a (deterministic across runs, null-byte-separated)
- waitpid EINTR retry loop (prevents zombie processes under signals)
- setenv save/restore between builds (prevents cross-package env leaks)
- install::install() wired into kappa build CLI (store + DB + generations)
- Zero-padded generation filenames (gen-0001, lexicographic sort correct)
- Hardcoded paths fixed: /tmp/kappa-build→paths::temp_dir()/build
- Hardcoded destdir: /kappa/temp/destdir→paths::temp_dir()/destdir
- ensure_directories() called at main() startup
- build subcommand: -j N, --root wired end-to-end

fix: fetcher security — fork+execve, hash verification, tar safety, CLI --help
...
B1: Replaced all std::system()/popen() with fork+execve — zero shell injection
B2+B3: Added sha256/sha512/md5 fields to PackageDef, parser support, actual hash comparison in verify_hash()
B4: tar --no-same-owner --no-same-permissions, zip uses unzip instead of tar
B5: Patch sha256 verified before application via -i flag (no shell redirect)
B6: kappa fetch --help now prints usage and exits 0
Also: removed dead ternary code, added <cstdlib>/<sys/wait.h>/<unistd.h>
