AOT: SQLite3::open returns null — leftover of version (#35991) (ext/sqlite3/sqlite3.c)

Problem

Thin AOT still has no SQLite3::open proxy after the version fold (#35991). Calls lower to an ExternalMethod null stub instead of php-src zim_sqlite3_open behaviour.

Host Zend in the CI image has no ext/sqlite3; compare VM vs AOT under PHP_COMPILER_PROFILE=8.4 (same gate as #35991).

Repro (PHP_COMPILER_PROFILE=8.4)	VM (2026-08-30 @ 78852fc5dd)	AOT
$db = new SQLite3(':memory:'); try { $db->open(':memory:'); } catch (Throwable $e) { echo get_class($e), ':', $e->getMessage(); }	Exception:Already initialised DB Object	silent NULL (no throw)
$db->close(); $db->open(':memory:'); then querySingle of folded SQL	reopen succeeds (void → null dump); DB usable	NULL stub; no reopen

php-src reference

• php/php-src ext/sqlite3/sqlite3.c — zim_sqlite3_open / Already initialised DB Object
• VM already correct: ext/sqlite3/SQLite3Open.php + VmSQLite3::openObject

PHP implementation target

• Register open on lib/JIT/Call/Sqlite3Method + Context sqlite3 proxies (peer of #35991 version)
• ext/sqlite3/JitSqlite3::open — if PROP_ID != 0 throw Exception; else re-init props like __construct after close (PROP_ID=0)
• No new runtime/*.c

Repro

./script/docker-exec.sh -- bash -lc 'export PHP_COMPILER_PROFILE=8.4
php bin/vm.php test/repro/sqlite3_open_aot.php
php bin/compile.php -o /tmp/o.bin test/repro/sqlite3_open_aot.php && /tmp/o.bin'

Done when

• VM and AOT match on already-open throw + close/reopen
• ./script/aot-smoke.sh stays 8/8
• No new thin C ABI

Parent

• Leftover of AOT: SQLite3::version() returns NULL — leftover of escapeString (#35977) (ext/sqlite3/sqlite3.c) #35991 / tracking Tracking: AOT correctness inventory — 44 mismatches in 85 probes across two language areas #31968 (closed) / Stdlib: SQLite3::open/backup/createAggregate/createCollation/loadExtension/version/lastError* still missing after #19862 (ext/sqlite3/sqlite3.stub.php) #20565
