KeiSeiKit-1.0/_primitives/_rust/kei-atom-discovery/Cargo.toml
Parfii-bot 990f5e3711 fix(substrate): E1 — kei-atom-discovery shared crate + 4 critical security fixes
Extracts authoritative atom discovery + frontmatter parsing into new crate
_primitives/_rust/kei-atom-discovery/. kei-sage and kei-runtime now both
consume the same implementation, eliminating Frontmatter drift.

Resolved findings:
- F-3/crit#3: path traversal via md_dir.join() — safe_join helper rejects
  absolute paths + .. components + post-canonicalise escapes (4 sites)
- crit#6/architect P0-a: Frontmatter drift — single AtomMeta struct
- SA supply-chain: serde_yaml archived — migrated to serde_yaml_ng 0.10
- crit#2: JSON Schema $ref SSRF — jsonschema 0.17→0.18 with resolve-file
  feature only, custom LocalFileResolver denies non-file:// schemes
- F-4: symlink traversal — walkdir follow_links(false) explicit everywhere
- F-5: YAML billion-laughs — 64 KiB pre-parse cap

Tests: 9/9 new crate + 23/23 sage + 2/2 runtime + 7/7 kei-task = 41/41 green.
