Fixes#221 - SQLite Memory Override bug.
This PR resolves memory overwrite behavior in autosave paths by replacing fixed memory keys with unique keys, and improves short-horizon recall quality in channel runtime.
**Root Cause**
SQLite memory uses a unique constraint on `memories.key` and writes with `ON CONFLICT(key) DO UPDATE`.
Several autosave paths reused fixed keys (or sender-stable keys), so newer messages overwrote earlier conversation entries.
**Changes**
- Channel runtime: autosave key changed from `channel_sender` to `channel_sender_messageId`
- Added memory-context injection before provider calls (aligned with agent loop behavior)
- Agent loop: autosave keys changed from fixed `user_msg`/`assistant_resp` to UUID-suffixed keys
- Gateway: Webhook/WhatsApp autosave keys changed to UUID-suffixed keys
All CI checks passing.

* feat: add OpenTelemetry tracing and metrics observer
Add OtelObserver that exports traces and metrics via OTLP HTTP/protobuf
to any OpenTelemetry-compatible collector (Jaeger, Grafana Tempo, etc.).
- ObserverEvents map to OTel spans (AgentEnd, ToolCall, Error) and
metric counters (AgentStart, ChannelMessage, HeartbeatTick)
- ObserverMetrics map to OTel histograms and gauges
- Spans include proper timing via SpanBuilder.with_start_time
- Config: backend="otel", otel_endpoint, otel_service_name
- Accepts "otel", "opentelemetry", "otlp" as backend aliases
- Graceful fallback to NoopObserver on init failure

* fix: resolve unused variable warning and update Cargo.lock
Prefix unused `resolved_key` with underscore to suppress clippy
warning introduced by upstream changes. Regenerate Cargo.lock
after rebase on main.

* fix: address review comments on OTel observer
- Fix metric types: use Gauge for ActiveSessions/QueueDepth (absolute
readings, not deltas), Counter<u64> for TokensUsed (monotonic)
- Remove duplicate token recording from AgentEnd event handler
(TokensUsed metric via record_metric is the canonical path)
- Store meter_provider in struct so flush() exports both traces
and metrics (was silently dropping metrics on shutdown)

* fix(providers): use Bearer auth for Gemini CLI OAuth tokens
When credentials come from ~/.gemini/oauth_creds.json (Gemini CLI),
send them as Authorization: Bearer header instead of ?key= query
parameter. API keys from env vars or config continue using ?key=.
Fixes#194

* refactor(gemini): harden OAuth bearer auth flow and tests
* fix(gemini): granular auth source tracking and review fixes
Build on chumyin's auth model refactor with:
- Expand GeminiAuth to 4 variants (ExplicitKey/EnvGeminiKey/EnvGoogleKey/
OAuthToken) so auth_source() uses stored discriminant without re-reading
env vars at call time
- Add is_api_key()/credential() helpers on the enum
- Upgrade expired OAuth token log from debug to warn
- Add tests: provider_rejects_empty_key, auth_source_explicit_key,
auth_source_none_without_credentials
