Subject: [PATCH 2/2] Fix SpeedMapping 0.4 compatibility (drop 0.3 support)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

SpeedMapping 0.4 introduced breaking API changes:
- `converged::Bool` -> `status::Symbol` in return type
- `tol` -> `abstol`
- `Lp` -> `pnorm`
- `store_info` -> `store_trace`
- `σ_min` -> `initial_learning_rate`
- `orders::Vector{Int}` -> `orders::Tuple`

This commit updates the extension to use the 0.4 API exclusively
and changes the compat entry from "0.3, 0.4" to "0.4".
