fix(mysql): framework wire-compat — WordPress and Laravel run over the MySQL frontend - #11

…r the MySQL frontend Gate-5 testing (ephpm#188) pushed full WordPress 7.0 and Laravel 13 through the MySQL frontend for the first time and found nine gaps that made BOTH installs fail identically on rusqlite and turso backends: 1. handshake banner "5.1.10-alpha-msql-proxy" - WP >= 6.5 refuses; now reports a modern MySQL-compatible version string 2. index prefix lengths `col(191)` unparseable (7/12 WP core tables) 3. CREATE TABLE options (ENGINE/CHARSET/COLLATE) passed through to SQLite (killed every Laravel migration) 4. inline KEY/INDEX constraints emitted verbatim (5 more WP tables) 5. INSERT ... ON DUPLICATE KEY UPDATE col=VALUES(col) upserts 6. SHOW FULL COLUMNS missing/mis-shaped (WP read core options as '') 7. SQL_CALC_FOUND_ROWS / FOUND_ROWS() 8. information_schema existence probes (Laravel migrate gate) 9. qualified UPDATE t SET t.col = ... column references Plus a backend workaround: turso 0.7.0 pragma table-valued functions leave the connection in a phantom-transaction state where later writes are silently non-durable (tursodatabase/turso#7466 - upstream fix PR in flight from us; the sql_uses_pragma_tvf() heal is marked for removal when a fixed engine version is pinned). Evidence: with this patch, WordPress (install, theme render, posts, comments, options x100, generate 50, search-replace, plugin DDL) and Laravel (migrate, seed, CRUD, tx commit/rollback, rollback, re-migrate) run 20/20 green on BOTH engines - turso matches the rusqlite control exactly. 13 new regression tests cover every gap.
The wire-compat fix was functionally complete (test + clippy green) but the rustfmt check was red. This is `cargo fmt --all` output only — line-wrapping, trailing commas, import collapsing — no logic change.

Both upstream gates are now closed: tursodatabase/turso#7855 merged 2026-07-16 (merge commit f2ba5a2) and ephpm/litewire#11 merged as 699e634. All turso pins move from the mutable fork branch luthermonson/turso@fix/pragma-vtab-txn-state to the immutable upstream main merge commit. Re-verified on the upstream rev with the heal still disabled: all 44 litewire-turso tests pass, including the incident regression pragma_tvf_read_does_not_poison_session. Remaining unwind waits only on a turso crates.io release containing f2ba5a2.

Closes the nine wire-compat gaps found by ePHPm's Turso gate-5 testing (ephpm/ephpm#188) — full WordPress 7.0 and Laravel 13 installs failed identically on BOTH backends, proving the gaps were frontend/translation-layer, not engine. Details in the commit message.
With this patch both suites run 20/20 green on rusqlite AND turso (turso == control exactly). 13 regression tests.
Includes a clearly-marked workaround for tursodatabase/turso#7466 (pragma TVF phantom-transaction, data-loss class) — our upstream fix PR is in flight; the heal is annotated for removal once a fixed engine version is pinned.
Suites: litewire-translate + litewire-mysql 212 tests, litewire-turso 44 tests, clippy clean.
