feat(phase-c): resolve PHP-array-semantics phase-b TODOs

Resolve category K (array_* functions, integer keys, nested mutation,
sorting). Add shim variants (uasort over Vec<T>, uasort_map for IndexMap)
and delegate to existing typed variants (strtr_array, array_merge_map,
array_search_in_vec). Implement PHP array semantics directly where the
shape is fixed: canonical integer-key coercion (is_php_integer_key,
shared by config and FilesystemRepository::dumpToPhpCode), strict
array_search via trait-object pointer identity, array_reverse/array_chunk
preserve_keys loops, and the installed.php nested version mutations via
auto-vivify helpers.

Resolving the array_merge in UpdateCommand unmasked latent borrow bugs in
execute's tail (Rc input/output moved by value); fixed with .clone() to
match PHP reference sharing, and resolved the tightly-coupled Intervals
constraint check.

composerRequire reclassified to phase-c: it depends on the $GLOBALS
superglobal and PHP's require include mechanism, neither portable.
