feat: unified telemetry system (tracing, metrics, logging, profiling) (#26)

* deps: add OpenTelemetry, Pyroscope, and otelzap dependencies

* feat(telemetry): add TelemetryConfig with dev/prod defaults

* feat(settings): add telemetry settings category

* feat(telemetry): add shared OTel Resource with instance identity

* feat(telemetry): add OTLP exporter factory and no-op exporter

* feat(telemetry): add OTel provider factories (trace, metric, log)

* feat(telemetry): add MapCarrier propagation helpers for Wails bindings

* feat(telemetry): add ZapBackend bridging plugin-sdk Logger to Zap

* feat(telemetry): add Pyroscope profiling with plugin/controller labels

* feat(telemetry): add telemetry Service with init/shutdown lifecycle

* deps: add Grafana Faro and OpenTelemetry JS packages

* feat(telemetry): add TelemetryContext type and factory

* feat(telemetry): add unified frontend Logger with context enrichment

* feat(telemetry): add WailsTransport for Faro signal shipping

* feat(telemetry): add Wails binding instrumentation wrapper with trace propagation

* feat(telemetry): add useLogger and useTelemetryContext React hooks

* feat(telemetry): add console patching and public API module

* feat(telemetry): add Faro SDK initialization with WailsTransport

* feat(telemetry): add frontend OTel TracerProvider setup

* fix(telemetry): use resourceFromAttributes and setGlobalTracerProvider for OTel JS compatibility

* feat: wire telemetry service into app startup and replace CreateLogger

* feat: wire frontend telemetry init into app entry point

* feat(telemetry): add frontend signal ingestion and Wails binding

* feat(telemetry): register omniview application metrics

* test(telemetry): add end-to-end trace and log correlation integration tests

* fix: resolve undefined component in HomepageCard extension point rendering

The kubernetes plugin registers homepage cards with a `component` property,
but the normalization layer only reads `value`. Add fallback to accept both
property names, and fix HomepageCard to use the correct type and property.

* chore: add telemetry dependencies and generated Wails bindings

Adds go.mod deps for pyroscope, otelzap, otel-runtime, and otel/metric.
Includes regenerated Wails models and TelemetryBinding JS/TS stubs.

* fix: address PR review findings (batch 1)

- Use host.arch instead of os.arch for OTel semantic convention
- Add missing ResourceWatchActive assertion in metrics test
- Use os.UserHomeDir() instead of os.Getenv("HOME") for portability
- Don't panic on telemetry init failure, fall back to production logger
- Reset tracing provider to null on shutdown for clean re-init
- Return noop sink instead of throwing when telemetry not initialized
- Don't blindly prepend http:// to Pyroscope endpoint
- Revert unrelated .gitignore change

* fix: address PR review findings (batch 2)

- Derive telemetry settings defaults from DefaultConfig to prevent drift
- Use Options dropdown for LogsShipLevel with validation
- Mark auth_value as Sensitive with Password type
- Add hot-togglable log ship level via AtomicLevel + levelFilterCore
- Suppress spurious zap Sync errors on non-seekable fds
- Add float32/float64/uint/uint64 field conversions in ZapBackend
- Harden tests: exact profile types, global state save/restore,
  os.type + host.arch assertions, IsSampled check
- Fix logger merge order so user fields override built-ins
- Run instrumented fn inside span context via context.with
- Add recordException assertion in instrumentation tests
- Make patchConsole idempotent with robust arg serialization
- Surface transport/sink errors in dev mode
- Fix HomepageCard generic typing to eliminate double cast

* fix: address PR review findings (batch 3)

- Make ValidLogLevels unexported; add GetValidLogLevels() safe accessor
- Add require.NotNil(t, m) guard in metrics_test before field access
- Use semconv.OSTypeKey / HostArchKey instead of ad-hoc attribute.String
- Swap global OTel providers to noop before shutting down SDK providers
- Add span lifecycle assertions (setStatus OK, end) in happy-path test
- Export WailsBinding type for external consumers
- Preserve Error stack traces in patchConsole serializeArg
- Use unpatched console ref in WailsTransport to prevent recursion

* fix: address PR review findings (batch 4)

- Consolidate validLogLevels to single canonical slice + derived map
- Make context.with a spyable mock and assert it's called in tests
- Make patchConsole fail-open: sink errors swallowed via try/catch
- Defer patched=true until after all wrappers assigned successfully
