Checkpoint re-hashes all tracked files, stores changed blobs, and
updates per-file timestamps only when content changes. Missing files
are skipped gracefully. Status compares each tracked entry against
the filesystem and reports ok/modified/missing.
CLI: sgard checkpoint [-m message], sgard status.
4 new tests (changed file, unchanged file, missing file, status).

Garden package ties manifest and store together. Supports adding
files (hashed and stored as blobs), directories (manifest-only),
and symlinks (target recorded). Paths under $HOME are stored as
~/... in the manifest for portability. CLI init and add commands
wired up via cobra.
8 tests covering init, open, add for all three entry types,
duplicate rejection, HashFile, and tilde path expansion.

Manifest package (5 tests): Manifest/Entry structs with YAML tags,
New(), Load(), Save() with atomic write.
Store package (11 tests): content-addressable blob store keyed by
SHA-256, Write/Read/Exists/Delete with atomic writes, two-level
directory layout, hash validation.
Both implemented in parallel worktrees and merged.

Implements Manifest and Entry structs with YAML tags, New() constructor,
Load(path) for reading, and Save(path) with atomic write (temp file +
rename). Tests cover round-trip serialization, atomic save cleanup,
entry type invariants, nonexistent file error, and empty manifest.

Remove all old C++ source files, proto definitions, CMake build,
clang configs, IDE files, and Trunk linter config. Initialize Go
module (github.com/kisom/sgard) with cobra and yaml.v3 deps.
Set up cobra root command with --repo persistent flag.
