Migrating from 0.33.0

Version 0.33.1 introduced new crates.io package names. Cargo package names do not migrate automatically.

# Before
tracing-otel-extra = "0.33.0"
tracing-opentelemetry-extra = "0.33.0"

# After
tracing-otel = "0.33.1"
otel-init = "0.33.1"

Update Rust import paths at the same time:

// Before
use tracing_otel_extra::Logger;
use tracing_opentelemetry_extra::OtelGuard;

// After
use tracing_otel::Logger;
use otel_init::OtelGuard;

axum-otel keeps its package and import name, but version 0.33.1 depends on tracing-otel internally.

Also verify explicit tracing-otel features. The crate has no default features: use logger for code-based Logger, env for Logger::from_env, or the narrower HTTP features listed in Cargo features.

If the application is upgrading from an older HTTP-span release, migrate dashboard and alert field names using the table in HTTP span attributes.
