chore(phase0): name validation, golden frames, daemon into library tree, TSan daemon lane

Item 8a — ConfigValidator warns on non-identifier variable/event/alarm/
command names ([A-Za-z_][A-Za-z0-9_]*): language bindings expose names as
kwargs/attributes, so 'Chamber Pressure' would be unusable in the planned
Python client. Warning not error — the wire doesn't care. Tested (4 warning
sites + good-name negative).

Item 4 tail — golden frames for S5F1 (Binary ALCD / U4 ALID / ASCII ALTX)
and a composed S6F11 (the production-critical report shape), bytes hand-
computed from E5 encoding rules: external pins on message composition.

Item 7 — equipment_service.hpp moved to include/secsgem/daemon/ (apps/
include-path hack removed) and a TSan daemon lane added locally + in CI.
tools/tsan.supp suppresses races whose accesses sit entirely inside the
UNinstrumented system libgrpc/libgpr/libabsl (epoll wakeups, absl Mutex
GraphCycles bookkeeping); our frames stay fully checked. The lane earned its
keep on first run: it caught a REAL threading-contract violation — a daemon
test reading model stores from the test thread while the io thread serviced
posted writes — fixed to use read_sync, exactly per the documented contract.
Now TSan-clean under halt_on_error=1 in the full production threading shape.

Suites: core 470/3068, daemon Release+TSan 125/125 each.
