Subject: [PATCH] fix(ci): maturin manifest-path is Cargo.toml not
 pyproject.toml

maturin>=1.5 requires -m to point to Cargo.toml, not pyproject.toml.
Fixes wheel build job failure in CI (all three matrix targets).
Also switches to manifest-path: action param for cleaner workflow syntax.
Applies same fix to Makefile build-wheel and develop targets.
