[1.0.0] — 2026-02-14

/proc/<pid>/maps parser — fast, zero-copy line-by-line parser that extracts all memory region metadata (addresses, permissions, offset, device, inode, pathname).
/proc/<pid>/smaps parser — optional enrichment with per-region RSS, PSS, shared/private page counts, and swap usage.
Region classification — automatic categorisation of regions into heap, stack, code, shared_lib, mapped_file, anonymous, vdso, vvar, vsyscall, and unknown.
System-wide snapshot (--all) — enumerate every process on the system, with per-process snapshots and a list of skipped (permission-denied) processes.
Periodic sampling — background-threaded sampler with configurable interval, snapshot count, and ring-buffer history.
Snapshot callbacks — register on_snapshot callbacks for real-time processing during periodic collection.
JSON output — ordered JSON via nlohmann/json with pretty-print (default) or compact (--compact) modes.
CLI flags — --smaps, --interval, --count, --output, --compact, --skip-kernel, --help, and --version.
Library API — use memc_lib as a static library in your own CMake project; link with target_link_libraries(your_target PRIVATE memc_lib).
CMake install rules — install(TARGETS …) for the CLI binary, static library, and public headers. CMake package-config files are exported so downstream projects can find_package(memc).
