* test(engine): regression tests for #283 camelCase property filters Red against current code. A query (or chained mutation) that filters on a camelCase schema field lints and plans cleanly but fails at run time with "No field named reponame" because the identifier's case is destroyed at the engine->Lance boundary. Coverage added: - query.rs unit: ir_filter_to_expr on a camelCase property must emit an Expr::Column named `repoName`, not `reponame` (red); plus a green coercion guard that a camelCase int column still gets a coerced literal. - mutation.rs unit: predicate_to_sql must emit the column UNQUOTED and case-preserved (green guard documenting the committed-scan contract). - literal_filters.rs e2e: a camelCase @index field with an inline-binding pushdown filter returns the seeded row (red — read pushdown). - writes.rs e2e: an update+delete on a camelCase predicate, and a chained update that re-reads the pending side of scan_with_pending by the same camelCase predicate (red — pending MemTable scan).

Read pushdown (exec/query.rs, ir_expr_to_expr): build the column reference with datafusion::prelude::ident() instead of col(). col() routes through SQL identifier normalization and lowercases an unquoted identifier (`repoName` -> `reponame`); ident() builds an unqualified, case-preserved Column. Property refs here are always bare column names, so there is no qualified-name handling to lose. No-op for the lowercase columns that work today. Pending mutation scan (table_store.rs, scan_pending_batches): the committed-scan consumer (Lance Scanner::filter(&str)) preserves an unquoted identifier's case but treats a double-quoted "col" as a string literal, so predicate_to_sql must keep the column unquoted. The pending side splices that same unquoted predicate into a DataFusion `SELECT ... WHERE`, which would lowercase it. Make that path case-preserving by disabling sql_parser.enable_ident_normalization on its SessionContext rather than quoting (quoting would match zero committed rows). predicate_to_sql gains only a clarifying comment; its emitted string is unchanged. Full engine suite green (579 tests).

Linked from a new "Case Studies" section in the dev index so the link check passes.
