Matthew Jackson 49011d577f labels/deluxe: decode real per-stream labels, emit High (Universal + others) ...

The Deluxe parser detected com/bydeluxe discs but emitted nothing, so
mpls_universal won at Low. Grounding the decoder on real Universal discs
(Fast Five / F9 / Bourne, studio="uni") surfaced three defects that
kept the full Phase A-D pipeline from ever resolving a stream on any
real disc, all fixed here:

1. Master enums were keyed by the ZIP ENTRY name ("pd.class") but the
   binding class references enum constants by JVM INTERNAL name
   (getstatic pd.<field>), so Phase C's getstatic count never matched
   the identified enums and found zero binding classes. Key master enums
   by this_class_name instead.
2. MasterEnumTable resolved getstatic operands by enum VALUE string
   ("English") but the operand is the obfuscated static-FIELD name
   ("a"), so every language/purpose ordinal came back unresolved.
   Capture the ordered putstatic field names (clinit_enum_field_names)
   and key the resolver on them.
3. The Language-enum fingerprint demanded 70+-4 values; Universal's
   enum has 65, so Phase A rejected it outright. Give each fingerprint
   its own count window (Language widened to span 65 and 70); the
   ordered 4+-string prefix stays the real discriminator.

Also: model anewarray/newarray so array construction keeps the symbolic
stack aligned, and skip constructors with an array parameter so the
Universal title-wrapper object (oq.<init>(...,[Lnp;,[Lwb;,...)) is not
mistaken for a subtitle binding. Recover SDH/RNIB from the language
display name (Universal encodes it as a distinct Language value, not a
Purpose). Add config.xml <TitleConfig studio="..."> detection. Raise
confidence to High when the binding table decodes >=1 stream; the
mpls_universal floor still back-fills un-named STN slots.

Fixtures: verbatim pd/lp/tl .class files from FastFive.iso decode to
English/French/Spanish + English Commentary (Dolby Digital) audio and
per-title eng/spa/fra subtitles. Validated end to end: labels-analyze on
FastFive/F9/Bourne now reports parser=deluxe High with real per-stream
languages, names, purposes and codecs instead of mpls_universal Low.
