ref(vortex-io): unify cloud object storage api

[m7kss1]

Summary

Cloud object store construction was duplicated across vortex-jni, vortex-python,
vortex-duckdb each with different scheme coverage and credential behavior

New API

/// Resolve any URL or path
let vxf = session.open_options().open_url("s3://bucket/key/file.vortex").await?;

/// Typed result for callers that need the store directly
let (store, path) = FileLocation::resolve(url)?.into_remote()?;

CLI: now remote files work out of the box:

$ AWS_REGION=us-east-1 vx query s3://bucket/hits.vortex --sql "select count(*) from hits"
$ vx tree gs://bucket/hits.vortex
$ vx browse az://bucket/hits.vortex

Closes: #000

Testing

AI disclosure: XXX

note: verified only on s3-compatible storages, azure and gcs remain untested for now
