feat: execute typed aliased inner-join reads

[omer-cengel]

Summary

Expand generated read queries to execute type-safe table aliases and simple inner joins while preserving deterministic projection and parameter ordering.

Changes

• Resolve base and joined tables through an ordered source scope with case-insensitive exposed names.
• Support qualified and uniquely resolvable unqualified columns, *, and qualified wildcards.
• Validate bare and explicit inner joins with one qualified column equality connecting each new source to an earlier source.
• Diagnose ambiguous columns, unknown qualifiers, duplicate source names, and unsupported join shapes.
• Map generated result rows by one-based projection position so duplicate column names remain distinct.
• Add generated-source compilation and H2 execution coverage for aliased, one-join, and multi-join reads.

Scope and non-goals

This change applies to supported :one and :many reads. It does not add outer, cross, natural, lateral, comma, USING, semi, apply, straight, global, windowed, hinted, or dialect-specific joins; compound join predicates; derived sources; computed projections; result-expression aliases; write-query joins or aliases; new query types; or runtime and configuration API changes.
