Post-review cleanup round:
- leaf.go: required validation now matches leafArgs inclusion rules
(LeafInt explicit 0 / LeafInt64 <= 0 count as missing) via
leafHasEffectiveValue; fallback-chain candidates are judged after
TrimSpace when Trim is set so pure-whitespace values fall through.
- command_meta.go: drop catalogStringVal/catalogStringSliceVal in favor
of existing schemaString/schemaStringSlice.
- fetch_mcp_metadata: cross-owned canonicals skip name-coincidence
direct merges; the reviewed cross-server identity is the sole source.
alias-vs-alias collisions in the command meta lookup now resolve to the
owner with the lexicographically smallest primary path instead of map
iteration order. Move catalogStringVal next to its sibling helpers in
command_meta.go and drop the redundant captureBaseHelpFunc alias in the
calendar help wrapper. Unify the Safety help annotation to English
"(requires --yes)".
ResolveMeta copies Catalog aliases into CommandIdentity and registers each
alias path against the same metadata (primary cli_path wins on collision),
so compat paths like 'report list' resolve instead of returning ok=false.
