Fills four documentation gaps surfaced by the doc audit:
1. README "Documentation map" was missing VERIFICATION.md (the file
that backs the proof-of-feature-completeness claims) and is now
pointing at the new files added in this commit too — ARCHITECTURE,
GLOSSARY, FAQ, examples/pvd_tool/ (the last two land next).
2. interop/README.md only documented secsgem-py. Three of the five
external validators (tshark, secs4j, libFuzzer) plus the E5 KAT
were invisible from the directory's own README. Rewritten as a
complete index — what's external, what each catches, how to run,
what bugs they've already surfaced, when to add a new validator.
3. GLOSSARY.md is new. Every SEMI acronym used in the codebase or
the docs gets one row: SVID, DVID, CEID, RPTID, ALID, ECID, PPID,
MID, CARRIERID, PRJOBID, CTLJOBID, SUBSTID, OBJSPEC, OBJTYPE,
MDLN, SOFTREV, EQPTYP, DATAID + every ACK code (COMMACK, ONLACK,
OFLACK, HCACK, CMDA, ACKC5-7-10, DRACK, LRACK, ERACK, EAC, TIACK,
GRANT, ALCD, OBJACK) + stream/function shorthand + HSMS terms +
T-timers + E84 signals + the standards lineup + codebase shortcuts
("the model", "the router", "the proof", etc.). Cuts week-1
onboarding time.
4. FAQ.md is new. Canonical answers to the questions that come up
once per integration: why HSMS unencrypted, SVID vs DVID, PJ vs
CJ, who fires FSM transitions, what runs on which thread, how to
add a new SECS-II message, ASCII vs Binary, common MES quirks,
how spool works, robustness fuzz vs libFuzzer, conformance vs
interop, what's not implemented.

Adds a Docker-based interop harness that drives the C++ server with
secsgem-py 0.3.0 as the active host and probes a secsgem-py-passive
equipment from a minimal C++ active client. Surfaces and fixes four
interoperability bugs uncovered by cross-testing:
* SEMI E5 identifier formatcodes are a U1|U2|U4|U8 wildcard;
secsgem-py picks the narrowest fitting width while our parsers
only accepted U4. `as_uN_scalar` / `as_iN_scalar` now accept
any unsigned/signed width and range-check the downcast.
* PPBODY (S7F3/F6) is "ASCII | Binary | List" per the spec;
secsgem-py defaults to ASCII. Added BINARY_OR_ASCII codegen
item type with `as_text_or_binary` accessor.
* S1F23/F24 Collection Event Namelist was unimplemented; added
schema + `vids_for(ceid)` accessor on EventReportSubscriptions
plus the dispatch handler.
* S10F1 was registered as a host->equipment handler, but per
SEMI E5 §12 S10F1 is equipment->host; S10F3 is the actual
host->equipment Terminal Display Single. Added an S10F3
handler alongside (we keep S10F1 too for backward compat).
