Migrate async runtime from async-std to tokio (required by libsql),
then add a mtime-based libsql cache at .nbd/cache.db that accelerates
nbd list, nbd ready, and nbd next by avoiding redundant file reads.
- Cargo.toml: replace async-std with tokio + libsql = "0.6"
- src/store.rs: async_std → tokio fs API; add open_cache() and
list_tickets_cached() with fallback to list_tickets on error
- src/main.rs: tokio::main, tokio::fs::remove_file; wire cmd_list,
cmd_ready, cmd_next to list_tickets_cached
- src/tests.rs: async_std::test → tokio::test, async_std::fs → tokio::fs

Tickets can now be stored in four formats, selected with --ftype:
json (.json) — pretty-printed JSON, default, unchanged
md (.md) — Markdown body with TOML frontmatter
toml (.toml) — full TOML
jsonb (.jsonb) — CBOR binary via ciborium
Changes:
- store.rs: FileFormat enum, detect_format(), find_ticket_path(),
per-format serialize/deserialize helpers; read_ticket/list_tickets/
resolve_id/migrate_tickets all scan all known extensions
- main.rs: --ftype on create (default "json") and update (optional,
converts format and removes old file); archive/update preserve
existing format when --ftype is absent
- tests.rs: update write_ticket/ticket_path call sites; add TOML,
Markdown, and CBOR roundtrip unit tests
- integration.rs: 8 new format tests covering create, list, update
conversion, format preservation, body roundtrip, unknown-ftype error
