83b020499b docs(research): #9 sweep acclient_function_map.md against PDB symbols
Pure-docs sweep. Cross-checked 63 hand-curated entries in
acclient_function_map.md against docs/research/named-retail/symbols.json
(the PDB-derived authoritative name table) using the new helper at
tools/pdb-extract/check_function_map.py.

Findings:
  - Zero entries matched address-and-name exactly. Confirms the
    PDB build is from a different revision than the binary that
    produced our Ghidra chunks (~0x800-0xC10 byte delta varies by
    function cluster). Match by NAME, not by raw address.
  - 38 entries corrected by PDB name lookup. The "Was" column
    preserves the old address for traceability against existing
    code comments. Old entries pointed mid-body of the actual
    function; new column heads point to function starts.
  - 25 entries have no PDB match. Either inlined / non-public
    (no S_PUB32 record) or our hand-derived names were synthesized
    from call-site analysis and don't match the MSVC mangled form
    in the PDB. Several had wrong class assignments (e.g. 0x5387C0
    claimed as CTransition::find_collisions, actually
    CPolygon::polygon_hits_sphere). Flagged for re-derivation in
    acclient_2013_pseudo_c.txt.

Pattern: kept the table format with two address columns (PDB +
legacy) so existing code references using the old addresses can
still be looked up. Added a sweep-summary section at the bottom of
the file documenting the methodology + findings.

Helper script at tools/pdb-extract/check_function_map.py is reusable
for future re-runs (re-run after every PDB regeneration / function
map edit).

Closes #9.
