fix: resolve all clippy warnings and fix test compilation errors
...
Address clippy pedantic/all lints: format_push_string in sqlite memory,
match_same_arms and match_wildcard_for_single_variants in anthropic
provider and prometheus observer, option_as_ref_cloned in main. Fix
pre-existing test compilation errors in gateway (missing max_keys arg
and trust_forwarded_headers field) and memory_store (missing security
arg). Add .worktrees/ to gitignore.

feat(observability): implement Prometheus metrics backend with /metrics endpoint
...
- Adds PrometheusObserver backend with counters, histograms, and gauges
- Tracks agent starts/duration, tool calls, channel messages, heartbeat ticks, errors, request latency, tokens, sessions, queue depth
- Adds GET /metrics endpoint to gateway for Prometheus scraping
- Adds provider/model labels to AgentStart and AgentEnd events for better observability
- Adds as_any() method to Observer trait for backend-specific downcast
Metrics exposed:
- zeroclaw_agent_starts_total (Counter) with provider/model labels
- zeroclaw_agent_duration_seconds (Histogram) with provider/model labels
- zeroclaw_tool_calls_total (Counter) with tool/success labels
- zeroclaw_tool_duration_seconds (Histogram) with tool label
- zeroclaw_channel_messages_total (Counter) with channel/direction labels
- zeroclaw_heartbeat_ticks_total (Counter)
- zeroclaw_errors_total (Counter) with component label
- zeroclaw_request_latency_seconds (Histogram)
- zeroclaw_tokens_used_last (Gauge)
- zeroclaw_active_sessions (Gauge)
- zeroclaw_queue_depth (Gauge)
