fix(ghidra): classify modern Swift manglings in swift type analysis (#1208)

* fix(ghidra): classify modern Swift manglings in swift type analysis

Categorize modern Swift 4.2+ manglings ($s, _$s) instead of dropping them
in analyze_swift_types. The classifier only accepted the legacy _Tt marker,
so procedure names reported by current providers produced an empty inventory.
Legacy _Tt families and behavior are unchanged. Fixes #1187.

* fix(swift): retain provider aliases and category unknowns

The optional Swift lane compiles a source-owned fixture and checks modern and
provider-demangled procedure names through real stdio MCP, with and without the
dSYM companion. It checks unfiltered, structs, and literal-name filters,
same-address alias evidence, deduplication, and explicit unresolved categories.
It does not add a Swift prerequisite to the host C fixture lane.
The host lane also verifies namespaced C++ ABI symbols and annotation identity.
That facet requires Ghidra's matching `demangler_gnu_v2_41` native component in
`GPL/DemanglerGnu/os/<platform>/` or `build/os/<platform>/`, in addition to the
