chore: bump version to 0.3.0

[panos-xyz]

Summary

Prepares the v0.3.0 release. Bumps [workspace.package].version from 0.2.2 to 0.3.0 and refreshes Cargo.lock so all 13 internal morph-* crates carry the new version.

Highlights since v0.2.2 (5 PRs):

• feat: morph_getTransactionHashesByReference RPC + morph-reference-index ExEx (feat(rpc): implement morph_getTransactionHashesByReference #106)
• breaking: removed engine_appendBatchSignature / BatchSignature — consensus already stopped calling it (refactor(engine-api): remove engine_appendBatchSignature and BatchSignature #105)
• chore: workspace build-profile gradient, prod deploys default to profiling, x86-64-v3 baseline for x86_64 release artifacts (chore: add workspace build profile gradient and wire prod deploys to profiling #104)
• refactor: dropped unreachable apply_curie_hard_fork dead code (refactor(evm): remove unused apply_curie_hard_fork dead code #101)
• fix(clippy): unnecessary_sort_by lint cleanup (fix(evm): use sort_by_key to satisfy clippy unnecessary_sort_by lint #100)

A breaking change (#105) plus a sizable new feature (#106) warrant a minor bump per pre-1.0 SemVer.

Test plan

• CI green on this PR (build + clippy + cargo-deny + tests)
• After merge, tag v0.3.0 from main and push to origin (GitHub release CI) and gitlab
• Push release/0.3.0 branch to gitlab for deployment

Minor versions wild and free,
