The nuxt-3 test app runs with span streaming enabled, so cache spans now
carry the low-cardinality `cache.{operation}` name instead of falling back
to the cache keys. Also assert the newly emitted `cache.operation`
attribute, since the span name is derived from it.

… suites The streamed expectations these suites gained were written before #23830 landed, so they still expected cache spans to be named after the cache key and carried no `cache.operation` attribute. Name them after the cache operation the hook now uses, and fold the repeated peer/operation attributes into a `cacheSpan` helper so the two cannot drift apart again.

node-redis v4 writes its `localhost:6379` socket defaults back into `client.options`, v5 does not. Reading the options as-is therefore reported `server.address`/`server.port` for a v4 client and neither for the identically configured v5 one — so the same client got `SET localhost:6383` on v4 and the bare `redis` fallback on v5 once span names became low cardinality. Resolve the connection the way node-redis >= 5.12 reports it on its own diagnostics channel instead: a TCP client falls back to `localhost:6379`, and a unix socket reports its path as the address and no port. Batch spans go through the same helper rather than repeating the option lookup. The redis-cache suite picks up the low-cardinality cache names from #23830 in the same pass.

With span streaming enabled, redis `db.query` spans are named
`{db.operation.name} {server.address}:{server.port}`. Redis has no SQL
statement to summarize and no collection to pair the command with, so
the connection is the only low-cardinality target left. The command and
its arguments stay on `db.query.text`. `db.namespace` is not used: for
redis it is the numeric database index.
| | static | streamed |
|---|---|---|
| ioredis | `set test-key [1 other arguments]` | `set localhost:6379` |
| node-redis | `SET test-key [1 other arguments]` | `SET localhost:6379`
|
| native DC | `redis-SET` | `SET localhost:6379` |
| unix socket | `SET test-key [1 other arguments]` | `redis` |
| `FCALL` | unchanged | `fcall my_func` |
| batch | `MULTI` / `PIPELINE` | unchanged |
| cache | unchanged | unchanged |
Changes:
- `FCALL`/`FCALL_RO` are named after the redis function
- New `db.stored_procedure.name` attribute holds that function name
- Skipped when the library redacted the function name
- Batch spans now also set `db.operation.name`
- node-redis clients always report `server.address` and `server.port`
- Cache span names untouched, already made low cardinality in #23830
- Streamed tests added to four redis suites
- `MIGRATION.md` entry added
node-redis v4 writes its `localhost:6379` socket defaults back into
`client.options`, v5 does not. The same client therefore reported a
connection on v4 and none on v5. Both now resolve it the way node-redis
>= 5.12 publishes it on its diagnostics channel, in both trace
lifecycles.
