6ba22a75f3 Revise [a4430d262b3e129d] to preserve legacy behavior of the imposter 
test-control.  The control argument must be 2 now to get read-only behavior.
The control argument of 1 goes back to the prior read/write behavior.

2ea861a245 In wasm.ptr.coerce(), treat the undefined value the same as 0 for Number-type pointers for consistency with the BigInt coercion. The bindings have long treated both null and undefined as === 0 for pointer operations.

22f9ca64db Get about 1/3rd of the tests running with MEMORY64=1, but the code noise level added by the BigInt/Number discrepancy is making this very unattractive. There are apparently irreconcilable differences between MEMORY64=1 and 2, in that they have different argument type expectations for methods such as WebAssembly.Table.get(), where MEMORY64=1 requires a BigInt a MEMORY64=2 requires a Number. We have no way to make that distinction from the JS code, and don't know what other APIs are affected by that quirk.

d6403a2d2e Initial experimentation with a -sMEMORY64=1 wasm build (full 64-bit). This compiles but does not pass tests due to friction between BigInt and Number types (e.g. Number(null)===0 but BigInt(null) throws, many functions are fussy about which of those types they'll take, and we cannot simply mix and match the two types transparently (1n+1 is not legal (but 1n>=1 is), so we can no longer do pointer arithmatic without hoop-jumping)). The library bootstraps but it's failing early on in tests due to this friction.

d4cc844a2b Diverse cleanups and docs in the JS and kvvfs pieces. Functional changes: (A) ensure that the 'i32' JS/WASM func arg/result conversion works properly with a 64-bit-memory WASM build (which we neither use nor test but [https://webassembly.org/news/2025-09-17-wasm-3.0/ | the newly-ratified WASM 3.0] brings within potential reach). (B) Fix sqlite3_js_posix_create_file() to not deallocate its input array if the client passes in raw memory (the library has never used it that way but the API permits it).

49a37f333a Improvements to imposter tables: (1) They are read-only unless writable-schema 
is enabled.  (2) Because they are now read-only, the ".imposter" command
in the CLI no longer requires the --unsafe-testing command-line option.
(3) Imposter tables do not participate in a PRAGMA integrity_check and hence
do not cause false-positive errors.  However, you can still do an
integrity_check on the the imposter table itself by naming the imposter
table as the argument to integrity_check.
