- Export: only export blocks present locally; skip missing (partial CAR). --local-only with --offline. Support both binary and base58 link keys. - Import: support partial CARs; --local-only with -- pin-roots=false (error if both --pin-roots and --local-only set). - Fix cidFromBinString to accept base58 key format from link implementations.

Thank you @ChayanDass, quick first pass review below.
Also, we need to wait for go-car release with your fix before this can be merged.

--local-onlytodag exportanddag importSummary
Adds support for partial CAR export and import: export only blocks that exist locally (skipping missing blocks), and import such partial CARs without pinning roots.
Changes
dag export--local-only(bool): When set, only blocks present in the local blockstore are exported; missing blocks are skipped (partial CAR). User must pass--offlineexplicitly for a local-only DAG walk; the command does not set offline automatically.dag import--pin-roots(bool, default true): Pin optional roots listed in the CAR headers after importing.--pin-roots=falseand--local-only(not both with pin-roots true).Usage
Export a partial CAR (local blocks only; user must pass both flags):
Import that partial CAR without pinning roots:
ipfs dag import --pin-roots=false partial.car # or ipfs dag import --local-only --pin-roots=false partial.carReferences
ipfs dag export --ignore-missing-blocks#10826, ipfs-webui#2380
