Merge master into cpp20-modernization (RPC fix, auto-bootstrap, tor_data fix)

Brings in:
- 79b0c4a: Fix RPC thread crash on bad auth (T001) — adapted to C++20 style
- d0fb2dc: Enable auto-bootstrap for GUI wallets
- 89a480a: Fix tor_data/state directory trap + make -notor work
- 372b252: Fix Windows CI shell for git submodule
- 6c56e41: Init secp256k1 submodule before build

Kept v5.9.9 version (cpp20-modernization's, newer than master's v5.9.7).
CI workflow kept cpp20-modernization's version (submodule init already present).
