fix: RSR compliance audit — license, SPDX, Containerfile, SCM, zero warnings

- License: AGPL-3.0-or-later → PMPL-1.0-or-later in Cargo.toml
- Author: hyperpolymath → Jonathan D.A. Jewell <j.d.a.jewell@open.ac.uk>
- SPDX: fixed 15 files (MIT OR Apache-2.0 → PMPL-1.0-or-later), added 3 missing
- Containerfile: Debian → Chainguard Wolfi multi-stage, non-root user, correct labels
- SCM: replaced stale language-bridges metadata with correct proof-of-work data
- Removed .machines_readable/ duplicate directory
- Removed duplicate Justfile, CONTRIBUTING.md, LICENSE.txt
- Removed philosophy badge from README (per policy)
- Updated README: Bevy 0.13→0.18, Rust 1.70→1.83, license MIT→PMPL
- Fixed unwrap() patterns in main.rs (tokio runtime) and client.rs (serde_json)
- Suppressed deprecated SelectableLabel warnings
- Suppressed dead code warnings for in-development game modules
- Added .github/CODEOWNERS, .well-known/ (security.txt, humans.txt, ai.txt)
- Created casket-ssg one-page site
- Zero warnings, 20 tests passing
