Adds an MSVC name-demangling layer in front of M3's vtable / RTTI work:
- New `xenia_analysis::demangle` wraps the `msvc-demangler` crate (a Rust
port of LLVM's `MicrosoftDemangle.cpp`). `demangle()` short-circuits on
non-mangled inputs (`?` prefix check); `demangle_or_raw()` always returns
a record (raw passthrough on parse failure).
- Heuristic split of the formatted demangled string into structured fields
`(namespace_path, class_name, method_name, params_signature)`. Top-level
paren / template-bracket aware, so `a::b<c::d>::e` and signatures with
templated arg types parse correctly.
- DB: new `demangled_names(address, mangled, raw_demangled, namespace_path,
class_name, method_name, params_signature)` with indices on address /
class_name / method_name. Populated from any label whose name starts with
`?` plus any import name that happens to be mangled.
For Sylpheed (a fully stripped binary) this table is empty out-of-the-box;
the layer's value lands in M3, which will append rows for every RTTI
TypeDescriptor name found in `.rdata`.
Tests 610→617 (+7 demangler unit tests covering early-out, raw fallback,
member function form, RTTI form, qname split, paren-template safety, and
top-level `::` splitting).

Adds an authoritative function-boundary source from the linker:
- New `xenia_xex::pdata` parses .pdata 8-byte entries (BeginAddress + packed
prolog/length/flags). Bit layout per Microsoft PE32 PowerPC spec: prolog in
bits 0..7, function_length in bits 8..29, flags in 30..31.
- `func::analyze_with_pdata` unions pdata BeginAddresses into the candidate
set, attaches `pdata_validated`/`pdata_length` to each `FuncInfo`, and trims
any function whose `end` overlaps the next start (catches mis-merge where
one row spanned two prologues — the audit-031 sub_824D23B0/sub_824D29F0
case).
- DB: extends `functions` with `pdata_validated BOOLEAN`, `pdata_length BIGINT`;
new table `pdata_entries`; index on pdata_validated.
- New `crates/xenia-analysis/SCHEMA.md` documents M1 layer + forward work.
Validation on Sylpheed: 25481 functions (was 12156) / 23073 pdata_validated /
0 orphans / 0 mis-merges. Audit-031 mis-merge resolved: sub_824D29F0 now has
its own row with `pdata_length=280` (70 dwords); sub_824D23B0 now correctly
ends at 0x824D2878 (`pdata_length=1224` matches prologue walk).
Tests 605→610. New 5-test pdata unit suite covers bit layout + sentinel +
out-of-range filtering + real-world layout round-trip.

The old src/ppc.rs that re-implemented PPC formatting collapses into
a 30-line shim that delegates to xenia-cpu's single-source-of-truth
disasm. A new disasm.rs wraps the shared iterator and feeds enriched
items (analysis context: function membership, xrefs, mnemonics) into
pluggable sinks.
Sinks split: text.rs (objdump-like output), json.rs (JSONL stream
matching the new xenia dis --json mode), duckdb.rs (the analysis DB
ingest). db.rs is restructured into ingest_instructions +
write_analysis_results so a run can stop after raw ingest, and a new
target_hex column lands on the instructions table. sql_views.rs adds
five additive views layered on top of the raw tables.
Tests: assert-based JSON-fixture goldens (disasm_goldens) and a
PRAGMA-table_info schema golden (db_schema_golden) covering all
ingested tables and the SQL views.
