0.13.14 has 80 commits from 7 contributors. Selected changes: Features:

• Add a PRQL-native implementation of append by:name, which aligns columns by name rather than position and works on any dialect. Columns present in one relation but not the other are filled with NULL. Supporting this added wildcard expansion of relations via their lineage, plus tuple_uniq and tuple_reverse. (@kgutwin, #6046) Fixes:
• Generate BETWEEN again. The optimization compared whole rq::Expr values, including their spans, so the same column referenced at two source positions never compared equal and a >= 5 && a <= 10 was left unoptimized. (@queelius, #5738)
• Don't leak a joined branch's sort into the implicit ORDER BY that take generates. A join now retains the left side's order, as documented, rather than emitting a column that is no longer in scope once the joined branch is materialized as a CTE. (@lukapeschke, #6015)
• Return a compile error instead of panicking when append is given relations with different numbers of columns, or with incompatible column types. (@prql-bot, #6025)
• Set the relation type of from_text earlier in the resolver, fixing a crash in infer_type_of_special_func. (@kgutwin, #6066)
• Give wrapper params unique names when currying through nested let-bound functions, which previously bound a curried argument to the wrong parameter. (@prql-bot, #5979)
• Escape quotes when a string contains both quote characters and one sits at each boundary, so formatted output lexes back to the original. (@prql-bot, #5987)
• Say "identifier" rather than "string literal" in the target error message. (@prql-bot, #6081)
• Sync the KSyntaxHighlighting and book highlighters with the std lib, and drop a stray sub-rule that wrongly highlighted f-strings. (@prql-bot, #6028, #6095) Documentation:
• Numerous typo, grammar, and stale-content fixes across the book, tutorials, bindings docs, and code comments. Integrations:
• Sync the prqlc Python type stub with the binding signatures. (@prql-bot, #6058)
• Correct ArgumentException constructor usage in the .NET binding. (@prql-bot, #5954)
• Bump the Elixir NIF's rustler crate to 0.38, matching the hex library. (@prql-bot, #6078) Internal changes:
• Publish to crates.io with Trusted Publishing. publish-to-cargo mints a short-lived credential per run through GitHub Actions OIDC instead of reading a stored token, so no long-lived publish credential exists. (@max-sixty, #6100)
• Update the tend (Claude-powered CI) workflows; most of this release's bot-authored fixes were filed by tend.
• Update the Rust toolchain version. (#6073)
