* feat(apps): add cache debug commands (+cache-get/-delete/-clear)
Add three apps-domain cache debug shortcuts for inspecting/clearing an app's
runtime cache:
- +cache-get: read a business key's value + metadata (hit/miss)
- +cache-delete: delete a single key (idempotent, write)
- +cache-clear: clear all cache in an environment (high-risk-write, --yes)
value renders raw on --format json, deserialized on --format pretty;
value_size_bytes is computed CLI-side; --environment auto-selects the branch
when omitted. Includes unit tests (hit/miss/dry-run/confirmation) and the
lark-apps cache skill reference.
* fix(apps): normalize cache numeric output fields and tidy comments
Follow-up hardening for the cache debug commands (+cache-get/-delete/-clear):
- Normalize ttl_ms / deleted_key_count via a new cacheInt() helper so
--format json emits a stable JSON number (or null) regardless of whether
the server sends the value as a number or a string. Aligns with the
repo convention that numeric wire fields may arrive as strings; previously
these were passed through raw, leaving the output type at the server's mercy.
- Add unit tests locking the string-wire -> JSON number contract for both
cache-get ttl_ms and cache-delete deleted_key_count.
- Tidy two comments: soften cacheBool's speculative "historical wire form"
claim to a defensive-tolerance note, and drop implementation jargon from
cache-delete's risk-level rationale.
