feat(plugin): generate the worker proxy stubs from the Composer sources

Replace the hand-written proxy stubs under crates/shirabe-php-rpc/php/stubs
with output of scripts/plugin-stub-generator, a deterministic emitter that
derives every stub from the Composer checkout and the classifier report.
Anything it cannot faithfully proxy (by-ref/variadic parameters, magic
methods, public properties, diverging omitted overrides, stale stub files,
a STUB_FILES entry missing in lib.rs) fails generation instead of degrading
silently, so future Composer releases surface new members as explicit
errors rather than silent gaps.

Regenerating the stubs also normalizes the hand-written inconsistencies
(uniform guarded constructors, import-based type spellings) and fixes real
gaps the review of the generated diff uncovered: the BaseIO authentication
methods now carry the real class's untyped signatures, and the previously
missing ConsoleIO::sanitize is materialized together with its private
static helper. A cargo test runs generate-stubs --check to keep the
committed stubs, the generator and the embedded list from drifting apart.
