'@sei-js/precompiles': major

**Breaking:** remove the IBC and Oracle precompiles. `IBC_PRECOMPILE_ADDRESS`, `IBC_PRECOMPILE_ABI`, `ETHERS_IBC_PRECOMPILE_ABI`, `getIbcPrecompileEthersV6Contract`, `VIEM_IBC_PRECOMPILE_ABI`, `ORACLE_PRECOMPILE_ADDRESS`, `ORACLE_PRECOMPILE_ABI`, `ETHERS_ORACLE_PRECOMPILE_ABI`, `getOraclePrecompileEthersV6Contract`, and `VIEM_ORACLE_PRECOMPILE_ABI` are no longer exported.

Neither precompile is supported on Sei any more, so calls to them fail on-chain regardless of where the address and ABI come from. There is no drop-in replacement: re-declaring them locally will not restore working calls, and code still depending on them needs to move off these precompiles.

[nit] This changeset is the release note downstream integrators will read, and "Neither precompile is supported on Sei any more" is the whole basis for the breaking change — but it points at nothing they can check. CON-283 / CON-205 are internal and won't resolve for them.

Consider linking a public source (docs.sei.io deprecation notice, or the sei-chain PR/upgrade that removed the precompiles) so integrators hitting a failed build can confirm the on-chain reality for themselves rather than having to take the note on faith. The rest of the wording is good — explicitly saying there is no drop-in replacement and that re-declaring the address locally won't help is exactly the right thing to tell someone who is about to do precisely that.
