python's GenericResource wires the whole generic command set, the glob
resolver and the VFS/FUSE ops from one table, and TypeScript had every
ingredient but no class that assembled them, so a custom backend there
was still written out by hand. Adds GenericResource<A>, generic over the
accessor so the table is checked against the core functions it holds
rather than against Accessor.
It keeps TypeScript's own wiring style: commands() and ops() return
arrays instead of python's register() loop mutating state in the
constructor. And there is no sdk.ts, because core's barrel is 99 lines
and gated in both directions while the ./* exports map already makes
every module importable, so the five names the new example and doc reach
for are the only additions to it.
Both classes gained sizes_always_known and supports_snapshot. Without
the first, no user-written backend could be mounted on FSKit at all,
since resolve_backend refuses a resource that cannot size its files.
The two one-file examples answer one shared truth file, so the two SDKs
cannot drift without a red build. docs/typescript/resource/new.mdx is
the twin of the python page, whose stale du_total/du_all is corrected to
du. The layout baseline drops to 255: resource/generic was one of the
counted divergences.
