Ensure that the OPFS VFS's xOpen() writes back the read-only flag to the output flags. Resolves the problem reported in [forum:cf37d5ff1182c31081 | forum post cf37d5ff1182c31081].

OPFS: if an op which needs a lock is called when no lock has been obtained, automatically lock it at the start of the op and unlock it at the end of that op. This is an attempt to alleviate the cross-tab contention described in [forum post 58a377083cd24a|forum:58a377083cd24a] but it increases speedtest1 run time by approximately 4x. Perhaps auto-lock can be combined with the older idle-time-based auto-unlock to unlock such locks (but not those from xLock()) to improve this?

Apply considerable acrobatics to get the JS/WASM deliverables building to and loadable from a directory other than the one which contains the app-level code. Requires an only-slightly-leaky abstraction of passing a URL argument when loading sqlite3.js but provides much greater flexibility in where the JS/WASM files are located.
