Extract the cast-based value conversion from txOutBaseParseJson into
a standalone documented helper. The ledger's Value type family resolves
to Coin for Shelley/Allegra and MaryValue for Mary onwards, requiring
a runtime type check via Data.Typeable.cast to bridge the gap.

Switch to herald for releasing

  Update dependency bounds to match CHaP revisions (PR #1344, PR #1342):
  - ouroboros-consensus ^>=2.0 -> ^>=3.0
  - plutus-core ^>=1.59 -> ^>=1.61
  - plutus-ledger-api ^>=1.59 -> ^>=1.61

Fixes #601. Links to dependency packages (cardano-ledger-*, plutus-*,
etc.) were relative paths pointing to directories that don't exist on
the hosted site, resulting in 404s.

Add a post-processing script that rewrites these relative links to
absolute URLs pointing at the correct external documentation sites.

Remove dcoutts, newhoggy, smelc, and kevinhammond from CODEOWNERS

Add per-era FromJSON instances for the experimental TxOut type,
mirroring the ToJSON structure. Pre-Alonzo eras parse address and
value only; Alonzo adds datum hash support; Babbage+ adds inline
datum (parsed from inlineDatumRaw with hash validation) and
reference script support. Supplemental datums are deliberately
unsupported as the ledger TxOut does not carry them.

Add ToJSON instance for new experimental TxOut
