docs(python): fix cross-references that resolved to the wrong page

`mkdocs build --strict` only catches references it cannot resolve. A bare
anchor such as `[limit][]` or `[vector search][search]` is matched by
autorefs against any heading on the site, so six of them silently linked
into the JavaScript reference instead. The relative links in
`permutation.py` and `remote/errors.py` pointed at in-page anchors and
paths that do not exist.

Targets that still exist here or in an imported inventory now use
mkdocstrings references; the guide pages deleted in #2770 use their
lancedb.com URLs.

 Add new columns with defined values.
 
-The `{ computed }` form stores the expression rather than evaluating it
-now: the column is committed with no values, and rows get them from
-[Table#refreshColumn](Table.md#refreshcolumn). Declaring one therefore costs the same on a
-large table as on an empty one.
-
-A refresh does not revisit rows it has already filled, so mutating an

         Maximum number of transforms to run concurrently.  Must be greater
         than zero.  When ``None`` (the default), uses ``os.cpu_count()`` or 1
         when the CPU count is unavailable.
-    on_transform_error:
-        What to do when the transform raises an exception:
-
-        - ``"raise"`` (the default): the exception propagates and iteration
-          aborts.
-        - ``"skip"``: the failing rows are dropped and iteration continues.
-        - ``"warn"``: like ``"skip"``, but a warning is logged for each
-          failing batch.
-        - a callable ``handler(exc) -> bool``: called with the exception;
-          return ``True`` to skip the failing rows or ``False`` to re-raise.
-          Useful to skip only expected error types (compatible with
-          ``webdataset.handlers`` style handlers).
-
-        When a batch fails, the transform is re-invoked on each single-row
-        slice of the batch so that only the rows that actually fail are
-        dropped.  Transforms should therefore be deterministic and accept
-        batches of any size (including one row).  Skipped rows are counted in
-        ``rows_skipped``.
-
-        Skipping weakens the elastic-determinism guarantee at the end of the
-        epoch: splits that lose more rows than others run dry earlier, and
-        each rank's iterator ends at the last cycle where every split *it
-        owns* still has a row.  Because bad rows are not distributed evenly
-        across splits, this means one rank's iterator can yield noticeably
-        fewer or more steps than another rank's *in the same run* — there is
-        no cross-rank coordination that stops every rank at the same global
-        step.  This is generally safe for asynchronous or single-rank use,
-        but synchronous distributed training (e.g. ranks that call
-        ``all_reduce`` every step) can hang or deadlock if one rank's
-        iterator is exhausted while others are still stepping; callers doing
-        synchronous multi-rank training with ``on_transform_error != "raise"``
-        are responsible for their own cross-rank stopping mechanism (e.g.
-        broadcasting a stop signal on ``StopIteration``).  The final few
-        global steps can also differ across topologies (bounded by the skew
-        in bad-row counts across splits).  The sequence of samples yielded
-        from each split remains deterministic.  Mid-epoch
-        checkpoints remain exact provided the transform fails
-        deterministically; in multi-rank training each rank must save its
-        own ``state_dict`` and the states must be combined with
-        ``merge_state_dicts`` before resuming on a different topology.
-        Prefer the ``filter`` parameter when bad rows can be expressed as a
-        SQL predicate (e.g. ``"col IS NOT NULL"``) — filtering happens before
-        splits are built, so every guarantee is fully preserved.

-        step, because each split's exact position is only known to whichever
-        rank owned that split, and the elementwise maximum needs every rank's
-        contribution to be correct.
