XYZhan de1976cf2d feat: let a table's maintained index set be changed in place ...

Changing the set meant unsetting the spec and setting it again, which drops
the MemWAL and everything in its fresh tier. `set_lsm_write_spec` now accepts
a repeat that differs only there and updates the set on the live index; the
sharding still cannot move, because the generations already written were
homed under it.

The default set also stops being a snapshot. It is stored as the intent to
maintain everything, which lance re-reads as the table changes, so an index
created later is maintained without another call. An index of a kind the
MemWAL cannot mirror is skipped under that intent rather than refusing the
table, since nobody asked for it by name; a named one is still refused.

The LSM read path asks the spec whether an index is maintained rather than
searching the stored list, which an unnamed set leaves empty -- reading the
list alone would refuse full-text and vector search on every table using the
default.
