Cardano Updates

Replace the hardcoded package list approach with an automated system that:
- Fetches the CHaP package index to classify packages as CHaP vs Hackage
- Auto-discovers all broken cross-package links in generated HTML
- Creates symlinks for versioned directory names (GHC-bundled and local)
- Rewrites links to known doc sites (prefix rules + exact overrides) or Hackage
- Validates all rewritten URLs with HTTP HEAD requests
- Replaces dead links with annotated plain text (tooltip shows package name)

This eliminates the ad-hoc hardcoded list, automatically handles new
dependencies, and guarantees zero broken clickable links.

Add HasCallStack to toConsensusQuery (calls
toConsensusQueryShelleyBased) and fromShelleyGenesis (calls
fromShelleyNetwork).

Add HasCallStack to calcMinFeeRecursive,
estimateOrCalculateBalancedTxBody, and constructBalancedTx, which call
balanceTxOuts, makeTransactionBodyAutoBalance, estimateBalancedTxBody,
and calculateMinimumUTxO that already carry the constraint.

Add HasCallStack to makeShelleyTransactionBody,
createAndValidateTransactionBody, fromLegacyTxOut, and toShelleyUTxO,
which call functions like mkCommonTxBody, toShelleyTxOutAny,
toShelleyTxOut, and createTransactionBody that already carry the
constraint.

Add HasCallStack constraints to functions that call makeShelleySignature
and castVerificationKey, so that call stack traces propagate through the
signing chain: makeShelleyKeyWitness, makeShelleyKeyWitness',
makeShelleyBootstrapWitness, makeShelleyBasedBootstrapWitness,
getShelleyKeyWitnessVerificationKey, makeKeyWitness, and
issueOperationalCertificate.

Bump ouroboros-consensus to ^>=3.0 and plutus to ^>=1.61

makeUnsignedTx: error when Plutus scripts present without protocol params

  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

convPParamsToScriptIntegrityHash silently returned SNothing when protocol
parameters were missing but Plutus scripts required computing the script
integrity hash. This caused downstream consumers (e.g. cardano-cli
build-raw) to produce invalid transaction bodies missing field 11
(script_data_hash).

makeUnsignedTx now returns Either MakeUnsignedTxError, and
convPParamsToScriptIntegrityHash explicitly checks whether the hash needs
to be computed before checking for protocol parameters.

Addresses IntersectMBO/cardano-cli#1363

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.
