chore(tokens): decommission 3 unused hidden-leaf spells

[a-monteiro]

Decommissions 3 unused hidden-leaf spells in tokens as part of the compute-optimization quick wins.

Each spell is hidden (hide_spells() -> dune.visible=false), a leaf (no other dbt/sqlmesh model, exposure, or curated-data reference -- only its own schema tests), and unused by customers (zero enterprise/paid queries over Jan-Jun 2026 in QES, below the negligible-free bar). Removed: tokens_goerli.nft, tokens_optimism.erc20_generated, and tokens_goerli.transfers. The two Goerli spells target a long-dead testnet.

Compute here is marginal -- this batch is hygiene/completeness alongside the daily and hourly batches where the real savings sit.

Schema edits were done by hand: tokens_optimism.erc20_generated only aliased anchors defined in the surviving tokens_optimism_erc20_curated (clean removal), and tokens_goerli.transfers was declared under a non-standard goerlils: key (a pre-existing typo that dbt already ignores) -- that key is left untouched aside from dropping the one model block. dbt parse is clean and surviving sibling models are byte-identical.

PR Summary

Low Risk
Leaf models with no remaining refs; impact is stopping unused pipeline builds, not changing live customer-facing tables.

Overview
Decommissions three hidden-leaf token spells that were already non-visible (hide_spells()), had no downstream dbt consumers, and showed no paid customer usage.

Deleted models: tokens_goerli_nft (joined curated NFT metadata with standards), tokens_optimism_erc20_generated (factory-derived receipt tokens from Aave, Granary, Yearn), and tokens_goerli_transfers (incremental enriched transfers on the defunct Goerli testnet). Matching tokens_goerli_schema.yml, tokens_optimism_schema.yml, and goerli/_schema.yml blocks for those models are removed; surviving Goerli models (e.g. tokens_goerli_nft_standards, tokens_goerli_base_transfers) are unchanged aside from a minor _updated_at description fix in the transfers schema file.
