Add a reusable GrpcMetricsLayer that can be applied to any tonic server
via Server::builder().layer() to automatically emit three Prometheus
metric families for every gRPC handler: started_total, handled_total
(with status code), and handling_seconds histogram.

Previously init_observability() called init_json_logger() (which set the
global subscriber with a fmt layer) and then init_tracing() (which only
set the global tracer provider). Because no tracing_opentelemetry::layer()
was ever added to the subscriber, #[instrument] spans never reached Tempo.
Now init_observability() builds a single Registry subscriber that
composes an EnvFilter, a JSON fmt layer, and an optional OTLP layer
(via tracing_opentelemetry). The OTLP layer gracefully degrades to None
when Tempo is unavailable, so logging always works.
Also adds build_otel_tracer() to tracing_config.rs which returns
Option<Tracer> for the caller to wrap in an OpenTelemetryLayer inside
their subscriber stack, letting the S type parameter be inferred
correctly by the compiler.

Web-gateway routing:
- Point TRADING_SERVICE_URL at api-gateway (proto mismatch fix)
Web-gateway uses foxhunt.tli.TradingService proto but was connecting
directly to trading-service which implements trading.TradingService.
api-gateway already proxies Subscribe* → Stream* correctly.
GitLab KAS:
- Disable gitlab_kas in appConfig to stop sidekiq NotifyGitPushWorker
errors (KAS pod was already disabled but Rails still tried to connect)
Trading service monitoring (3 stubs → real):
- AcknowledgeAlert: real alert lookup + state mutation in shared store
- GetActiveAlerts: returns actual active alerts from in-memory store
- StreamAlerts: now persists generated alerts (capped at 1000 entries)
Trading service ML streams (2 stubs → real):
- StreamModelMetrics: emits real inference_count, error_count, latency
per model every N seconds from the RuntimeModelInfo registry
- StreamSignalStrength: emits per-symbol signal aggregation from model
ensemble weights and latency confidence
Backtesting service:
- stop_backtest: real CancellationToken cancellation (was no-op)
Tokens stored per-backtest, execute_backtest wraps strategy call
in tokio::select! for immediate cancellation
Deleted 7 empty placeholder files:
- 4 Wave D regime stubs (dynamic_stops, ensemble, performance_tracker,
position_sizer) — comment-only files, never wired
- 2 Wave 3 feature stubs (microstructure, statistical)
- 1 PPO stub (unified_ppo.rs — empty struct definitions)

- Disable file logging in init_observability — use console-only (stdout).
Containerd captures stdout, Promtail ships to Loki. Eliminates
"Failed to create log directory: Permission denied" errors on 3 services.
- Remove LOG_DIR env vars and /app/logs emptyDir volumes from 5 deployments.
- Add OTEL_EXPORTER_OTLP_ENDPOINT=tempo to 5 services that were missing it
(api-gateway, web-gateway, data-acquisition, trading-agent, broker-gateway).
- Make OTLP tracing init non-fatal — services degrade gracefully if Tempo is
unavailable instead of failing entire observability stack.
- Stop web-gateway gRPC stream retry on Unimplemented status. When trading-service
doesn't implement streaming endpoints, log once and stop instead of retrying
every 60s indefinitely.

- init_observability now reads LOG_DIR env var for log directory (falls back
to relative logs/ path). Gracefully disables file logging if directory
cannot be created instead of failing the entire observability init.
- Add ServiceAccount, Role, and RoleBinding for ml-training-service to
create/get/list/watch/delete batch/v1 Jobs (K8s training dispatch).
- Add LOG_DIR=/app/logs env to ml-training-service, trading-service, and
backtesting-service deployment YAMLs.

Aliased re-exports avoid collision with existing types::Price/Quantity/Money
during migration. Will rename to canonical names in Phase 6 cleanup.

- Ratio arithmetic (Add, Sub, Mul, Div) now clamps overflow to
f64::MAX/f64::MIN instead of producing Inf from finite inputs
- Cross-type Price*Quantity→Money and Money/Quantity→Price use
saturating i128→i64 conversion via clamp instead of silent truncation
- Added clamp_finite() and saturating_i128_to_i64() helper functions
- Added 9 edge-case tests: 89/89 passing, clippy clean

- Add Serialize/Deserialize to all four financial types
- Ratio::ln returns 0.0 for non-positive inputs (prevents NaN leak)
- Ratio::exp clamps to f64::MAX on overflow (prevents Inf leak)
- Ratio::powi clamps to f64::MAX/MIN on overflow
- Add 4 invariant-preservation tests (80 total)

- Add dimension validation in DQN, PPO, Mamba2, TGGN, TLOB, Liquid,
KAN, xLSTM, Diffusion constructors (fail-fast on zero-dim inputs
that would cause CUDA_ERROR_INVALID_VALUE at runtime)
- Add num_unknown_features > 0 guard to TFT (temporal input required)
- Fix 12 dead-code/unused warnings in test compilation
- Remove opt-level=3 and codegen-units=1 from target rustflags
(was forcing O3 + single-thread codegen on dev/test builds)
- Remove hardcoded jobs=16 cap (cargo now auto-detects CPU count)
- Switch linker to clang+lld (2-5x faster linking)

Move 17 library crates into crates/, CLI binary into bin/fxt,
consolidate 10 test crates into testing/, split config crate
from deployment config files.
Root directory reduced from 38+ to ~17 directories.
All Cargo.toml paths and build.rs proto refs updated.
