Features

• Initial library (50dea4c)

Update notification and self-update for Python CLIs installed with uv tool, and the Python sibling of goselfupdate. Two layers used independently: notify prints one line a day and never raises, update installs a release and raises on failure.

Zero runtime dependencies, enforced two ways in CI: the declared list must be empty, and every core module must import in a virtual environment containing nothing else. That is why semver comparison is implemented here rather than taken from packaging, and why uv's receipt is read with tomllib. typer is an extra, confined to typercmd.

The API deliberately diverges from goselfupdate. Replacing a Go binary is safe under a running process, which holds an inode rather than a path; uv tool install --force rebuilds the venv the interpreter is living in, so update must be the last thing a process does and there is no background mode. What the two libraries do share is the state file schema, the environment variable contract, and version precedence.

Dev installs are detected from uv's own receipt rather than a version string. The installer knows how a tool got there and the running program does not, so this refuses local, editable and branch-tracking installs by reading what uv recorded at install time.
