Agent: add the corrective tools the toolbox was missing (#85 item 3)
The toolbox could create and move but not delete or resize; write the
journal but not read it; clear a whole bed but not pull one plant; report
seed remaining but not record a purchase. Close those gaps with thin
adapters over the SAME service methods the REST API uses, so they inherit
the permission checks unchanged:

  read_journal    → ListJournal   (the write/read asymmetry, most visible)
  update_object   → UpdateObject  (resize / rotate / rename / plantable)
  delete_object   → DeleteObject  (counterpart to create_object)
  remove_planting → UpdatePlanting (soft-remove ONE plop, like clear does)
  list_seed_lots  → ListSeedLots
  record_seed_lot → CreateSeedLot (record a purchase; "I bought 2 packets")

To address a single plop the agent needs its id + version, so
DescribePlanting now carries both — the same way DescribeObject.Version
already lets it edit an object. remove_planting soft-removes (removed_at =
today), mirroring clear_object, so the plant stays in planting history and
the change is undoable.

Deferred deliberately: an undo/revert tool needs a way to list recent
change sets to get a changeSetId, which is a larger addition; noted on the
issue for a follow-up.

Tested through the tool layer (TestCorrectiveTools): resize, single-plop
removal, journal read-back, seed-lot record+list, and delete.
