SAHPool VFS tweaks contributed off-list by Jure Rotar: hardening against malicious inputs and I/O errors. Truncate to the shorter length when overwriting a db file with a shorter one via importDb(). Correct xOpen() to honor the combination of CREATE/EXCLUSIVE flags.

Rework the JS kvvfs xLock(), xUnlock(), xCheckReserved(), and xSleep() analog to the recent opfs-sahpool changes to make it more robust when a given kvvfs store is accessed via multiple handles (all necessarily from the same thread). This does not break anything but also does not prove anything - tests are pending.

Do not inherit the OPFS SAHPool's xSleep method from the default VFS, as doing so can cause the thread to freeze. This VFS only deals with contention originating in the same thread, so xSleep() needs to be a no-op. Addresses [forum:3f0794c5d8|bug report 2026-09-30T12:52:54Z].

Add support for (make base64.wasm=1), which embeds sqlite3.wasm into its corresponding JS file as base64. A very expensive calculator which was fed the resulting file sizes assures me that the two-file approach is, in the aggregate, more efficient both in terms of overall network bandwidth (+~20% bigger for base64) and client-side memory usage (streaming vs non-streaming wasm compilation), so we'll shelve this as an interesting experiment or maybe for use by custom builds.

An initial attempt at embedding sqlite3.wasm into sqlite3.js using base64. This produces a chicken-egg situation in the build because the input file where the blob belongs is injested by emscripten (which generates the wasm file from which that blob is to be generated), so it does not work as-is but is being set aside for later. We'll need to add a second preprocessing step which uses a different #directive delimiter to keep it hidden inside the first pass, then squeeze the wasm file in through there.
