1//! Builder that assembles an [`AppContext`] from profile + config state.
2//!
3//! The builder owns the bootstrap order: profile -> paths -> files ->
4//! database -> logging -> extensions -> ancillary services. Failures at
5//! any step propagate as [`RuntimeError`](crate::error::RuntimeError).
6//! Subsystem resolution helpers live in [`assembly`].
