Namada libs v0.251.0 Consensus and API breaking release.

BUG FIXES

• Fix to receive IBC denom whose base token includes slash
  (#4643)
• Fixed a possible overflow of the masp expiration height in the SDK.
  (#4725)
• Allow to execute WASM with a tx payload that doesn't fit into the initial WASM
  memory. (#4729)
• Validate the base denom in MsgTransfer
  (#4733)

IMPROVEMENTS

• Display payment addresses instead of extended full
  viewing keys on the hardware wallet to save screen space.
  (#4436)

• Forbid targeting MASP payment addresses in IBC transfers.
  (#4593)

• Currently, the shielded wallet attempts to find a file and deserialize it, both of which are fallible. Upon failure,
  a default (empty) wallet is created. This is fine if the file is missing, but causes unexpeceted behavior when we've changed
  the wallet format and deserialize fails. This PR changes the logic to the following:

  • If the file is missing, use a default
  • If deserialization fails, try to run a migration (this requires versioning shielded wallets)
  • If deserializing / migration fails, error out explicitly

  (#4664)

• Added conversions cache

  • Conversions are cached when performing Masp balance queries. Futhermore, the decoded asset type cache is used more
  • effectively. Care must be taken to clear the masp conversions cache on load if the masp epoch has changed. If the
  • masp epoch changes during a balance query, it may produce invalid output. However, repeating the query after the epoch
  • has completed will yield the correct result. The new cache resides on the shielded wallet, so a migration has been added.

  (#4671)

• Perform wasm gas accounting using mutable global, to avoid frequent host/guest
  vm context switches. (#4685)

• When using the ledger client, we update witness maps manually. We now add notes to the witness map only if there were successfully trial decrypted. (#2693)

• Add backoff sleep between MASP indexer client failed requests.
  (#4702)

• Added a VP check that gov updated parameters are readable.
  (#4708)

• Allow bech32 encoding of MASP address in shielded receive middleware.
  (#4722)

• Improve the UX of Osmosis swaps in various ways. Moreover, start encoding the
  MASP address with bech32, rather than bech32m, when shielding the output
  of the trade. (#4723)

MISCELLANEOUS

• Make CometBFT max_tx_bytes configurable
  (#4712)

SDK

• Introduced the possibility to skip fee checks when MASP fee payment is
  expected. (#4730)

TESTING

• Added Cargo example that derives bounds on shielded reward parameters to
  ensure non-zero rewards (#4573)
