Subject: feat(external-packages,shim): implement impl todos across components

Port seld/jsonlint JsonParser (+hand-written Lexer), unblocking 10 json_file
parse-error tests verified byte-for-byte against PHP. Implement Symfony Finder
SplFileInfo, executable finders, String classes (byte/code-point/unicode),
ZipArchive shim (via the zip crate), SPDX license validation, and shim
date/stream functions. Genuinely-blocked sites (reflection, PHP runtime
constants, non-UTF-8 transcoding, recursive PCRE) stay todo!() with reasons.
