Crate aube_codes 

Stable identifiers for every error and warning that aube emits.

The crate is dependency-free on purpose: every other aube crate may depend on it. Codes are exposed as pub const &str so they can be used unmodified in tracing::warn!(code = aube_codes::warnings::X, ...), #[diagnostic(code = aube_codes::errors::Y)], and ndjson-emitting reporters without needing to call .as_str() or do any conversion.

Naming convention:

• ERR_AUBE_* for errors (anything that returns Err to the caller or aborts with a non-zero exit).
• WARN_AUBE_* for warnings (tracing::warn!) and non-fatal tracing::error! sites that don’t change exit status.

aube does not emit ERR_PNPM_* codes itself. Where a code maps cleanly onto a pnpm concept (lockfile, peer-deps, tarball, etc.) we reuse pnpm’s suffix under the ERR_AUBE_ prefix so the code reads the same to anyone familiar with pnpm — but the published code is always ERR_AUBE_*.

Codes are stable: once published, a code’s identifier and meaning must not change. Adding new codes is fine; removing or repurposing one is a breaking change.
