fix(pm): make bootstrap and bundle ownership explicit

Finish bootstrap uv before PM replaces its store entry. Keep failure
receipts stdlib-only and align the cryptography requirement and override
with the locked version.

Let bundle builders declare launch paths and update ownership. Remove
payload discovery, Store probing, and the unused develop command.
Derive Nix Python from the PM lock and share its provenance stamp.

Document setup, activation, optional dependencies, and distribution
ownership. Targeted Windows tests, relocated runtime launches, Electron
bundling, and bilingual docs builds pass. Native Nix and signed-package
acceptance remain CI gates.
