feat: add Query.Builder, aggregates, joins, and nested ON

[abnegate]

Why

Appwrite query-lib added aggregates, grouping, joins, extra spatial operators, and a POST /query body so large queries arrays are not capped by URL length. SDKs that already expose Query helpers need those methods, a fluent collector, and a way to nest JOIN ON conditions without leaking SQL.

What changed

• New Query helpers on every SDK that already had Query: aggregates (count, sum, avg, …), groupBy/having/distinct, joins (join/leftJoin/rightJoin/fullOuterJoin/crossJoin), extra spatial (covers, …).
• Fluent collector nested as Query.Builder where the language allows it (C#/Swift/Kotlin/Ruby/Python/TS namespace). PHP is Appwrite\Query\Builder imported as QueryBuilder. Go/Rust use package Builder with NewBuilder() / query::Builder. Dart cannot nest classes and must not export a top-level Builder (Flutter widget clash), so the type is QueryBuilder in lib/query/builder.dart.
• Nested JOIN ON: Query.on(...) plus join overloads that take an alias, an ON query, and extra filters. The wire shape is [alias?, Query.on, filters…].
• Client flatten is internal. There is no public Query.normalize. Flattening is structural (builder / nested query-string lists) and does not special-case the queries parameter name.
• Closed live-spec string enums encoded as type: string plus oneOf of single-value schemas are treated as wire enums. Untitled oneOf members take their name from the parent property.
• PHP from() and generated mocks wrap a scalar example for an array-of-enum field into a one-element list (OAuth prompt in the live spec is a string example on an array field).
• E2E QUERY_HELPER_RESPONSES covers each new helper in every SDK language test.

Raw/union/json/naturalJoin stay unexposed — those are not on the Documents validator allow-list.

Vector helpers were already on main; duplicate copies introduced during the rebase were removed so each language has a single definition.

Why this approach

A client-side JSON collector (not SQL) matches the existing Query string format {method, attribute?, values?}. Nesting the builder under Query keeps the public surface one type. Flattening inside the Client, without a queries key check, means any param that already carries query strings (join ON lists, having, or/and) is handled the same way.

POST /query itself lives in Appwrite (appwrite/appwrite#13300, stacked on #11649). SDK methods will be generated as createQuery once that spec is published.

Verified

• composer lint (phpcs PSR-12)
• composer lint-twig (djLint, 0 errors)
• composer refactor:check (Rector dry-run)
• Twig line length ≤ 1200
• composer test tests/e2e/PHP83Test.php — OK, 1511 assertions (includes array-enum scalar hydration)
• Generated Dart lib/ + tests/tests.dart analyze clean for the Builder/part-of/MockKind failures
• Generated Go query.NewBuilder().Limit(1).Build() compiles and prints the expected limit query

Not verified

• Full sdk-generator language e2e matrix on this HEAD. CI is the authority for that (previous HEAD was red on Dart/Flutter/Go Tests and Dart/Flutter/PHP/CLI Validation).
• Live Appwrite POST /query round-trip from a generated SDK (depends on appwrite#13300 + spec publish).
• CLI compiles in this repo against ../go via a replace in go.mod.twig (generated from the same spec as the CLI). Compiling the published CLI package against the last published Go module is not verified here.

• Adds language-specific Query builder implementations and package exposure.
• Adds aggregate, grouping, JOIN, nested ON, and spatial query helpers.
• Updates generated clients to flatten builders and nested query lists before serialization.
• Extends fixtures and end-to-end coverage across SDK targets.

Confidence Score: 5/5

The PR appears safe to merge because no blocking failure remains in the eligible follow-up review scope.

• These fixed scalar signatures cannot express the new nested JOIN ON form, and the facade exposes no on helper. Add on plus overloads/unions for (table, on) and (table, alias, on) so the typed callback can construct the nested wire shape supported by Query.

  join: (table: string, left: string, right: string, operator?: string, alias?: string) => string;
  leftJoin: (table: string, left: string, right: string, operator?: string, alias?: string) => string;
  rightJoin: (table: string, left: string, right: string, operator?: string, alias?: string) => string;
  fullOuterJoin: (table: string, left: string, right: string, operator?: string, alias?: string) => string;

templates/cli/internal/typegen/templates/databases.ts.hbs:44

• The facade delegates only the scalar join form and does not expose Query.on, so typed CLI callbacks cannot use the nested JOIN ON feature added by this PR. Mirror the nested overloads and on helper exposed by Query.

  join: (table, left, right, operator = '=', alias = '') => Query.join(table, left, right, operator, alias),
  leftJoin: (table, left, right, operator = '=', alias = '') => Query.leftJoin(table, left, right, operator, alias),
  rightJoin: (table, left, right, operator = '=', alias = '') => Query.rightJoin(table, left, right, operator, alias),
  fullOuterJoin: (table, left, right, operator = '=', alias = '') => Query.fullOuterJoin(table, left, right, operator, alias),

Went through Copilot's 29 threads.

Fixed

• Rust flatten no longer treats numeric nested arrays as query input
• Go flatten uses reflect.DeepEqual (no panic on [][]float64)
• Dart/Flutter flatten spreads [Query.builder()...] into a flat string[]
• Regenerating Rust deletes leftover src/query.rs
• Typed CLI QueryBuilder includes stddev/variance/bitwise aggregates
• Go skill examples match GroupBy([]interface{}) and 5-arg Join
• Skills drop createQuery until the spec has it, and only show build() into the generated string[] APIs

Left as-is

• CLI replace => ../go is for this generator (examples/cli + examples/go). Test-mode CLI omits it. The published CLI repo is a different tree.
• Generated service methods keep wire type string[]. Flattening is internal. Pass builder.build(). QueryInput stays on realtime, where a union already existed. Widening every query param is a separate API change and would still have to avoid a queries-key special case.

[abnegate]

Pushed two commits on top of the flatten-bugfix head:

• Language e2e tests now assert flatten: wrapped builders expand, nested numeric arrays stay nested, already-flat query lists stay lists. That is the coverage Copilot's flatten bugs needed.
• CLI generator testdata includes stddev/variance/bitwise so TestGenerateMatchesBaseline matches the typed QueryBuilder templates.

CLIGo126 / Validation cli (console) were red on the previous head because those baselines still expected groupBy at the old offset.
