Add NCC-13 software package release profile

[imattau]

Summary

• Implements Stage 11 of NCC-PLAN.md: NCC-13 (Software Package Release Profile). NCC-13 defines no new event — it profiles the existing NIP-51 Release Artifact Set (kind 30063) with package-manager metadata, so this adds an ncc13 module rather than redefining anything NIP-51/94/34 already own.
• New module modules/std/ncc13/0.1.0.nsm: the ReleaseArtifactSet event (kind 30063: d, a, version, version_scheme, channel, source, commit, repeatable requires/optional/conflicts, e, operator_for) and a minimal ArtefactMetadata event for NIP-94's kind 1063 carrying only NCC-13's own os/arch/format selectors.
• Twenty-two pure functions covering: extraction with the §8.4/§9.1 opaque/stable defaults, the two-column requires/optional/conflicts builder/readers, the ncc:13:publish operator_for claim (mirroring NCC-10's shape), a SemVer-§11 precedence comparator (prerelease-before-release, prerelease identifier comparison, build metadata ignored), single-constraint satisfaction (=/>/>=/</<=, relational operators scoped to semver only per §8.2/§8.3), and os/arch artefact matching with the any wildcard.
• Conformance: valid/invalid .ns fixtures, a pinned wire vector, a conformance/MATRIX.md row, and a worked examples/ncc13-release-monitor.ns bot (publish → upgrade-eligibility judgment → artefact selection), all exercised by new CLI tests plus a runtime unit test covering SemVer precedence and constraint satisfaction.
• Bumps the nostr-community-conventions pin from adad778 to 186c3ad (upstream added ncc-13; purely additive) across every existing ncc0X/ncc1X module and vector reference, and updates NCC-PLAN.md/ROADMAP.md/spec/README.md/spec/nostr.md accordingly.

Test plan

• cargo build --workspace — clean
• cargo test --workspace — all tests pass (249 passed, 1 ignored)
• cargo fmt --check — clean
• cargo clippy --workspace -- -D warnings — clean
• Manually ran every path documented in examples/ncc13-release-monitor.ns's header comment (nscript run with each event) and confirmed the printed output

CI's clippy check failed on 2cf6338: cloned_ref_to_slice_refs (&[value.clone()] where std::slice::from_ref(&value) avoids the clone) at two call sites in the new ncc13_release_functions_extract_compare_and_match test. This is a lint CI's clippy (1.98) enforces that the local toolchain here (1.94) doesn't yet have, so it wasn't caught before the first push. Fixed in 5a96258 — both call sites now use std::slice::from_ref, verified locally with cargo clippy --tests and the full test suite.
