ci: exclude Drive state transition action boilerplate from coverage

[QuantumExplorer]

What was changed

Added codecov exclusions for Drive state transition action boilerplate files in packages/rs-drive/src/state_transition_action/.

These files contain:

• mod.rs — Version dispatch enums with single-variant match arms delegating to V0 (match self { V0(v0) => v0.field })
• v0/mod.rs — Struct definitions + getter/setter trait impls (pure field accessors)
• transformer.rs (top-level) — Single-variant match delegating to V0::try_from(...)
• *_action_type.rs — Type enum definitions

NOT excluded: v0/transformer.rs files which contain real conversion logic (300-580 lines each).

Affected paths

Category	Files excluded
Token actions	token_burn, token_mint, token_transfer, token_freeze, token_unfreeze, token_claim, token_config_update, token_destroy_frozen_funds, token_emergency_action, token_direct_purchase, token_set_price_for_direct_purchase, token_base
Document actions	document_create, document_delete, document_replace, document_transfer, document_purchase, document_update_price, document_base
Identity actions	identity_create, identity_topup, identity_update, identity_credit_withdrawal, identity_credit_transfer, etc.
Contract actions	data_contract_create, data_contract_update
System actions	bump_identity_nonce_action, bump_address_input_nonces_action, partially_use_asset_lock_action, etc.

These are tested through drive-abci integration/strategy tests, not individually unit-testable.

📝 Walkthrough

Walkthrough

The pull request updates .codecov.yml to add ignore patterns for code coverage analysis, excluding various state transition action modules, transformer files, and enum definitions within the packages/rs-drive/src/state_transition_action/ directory structure from coverage reporting.

Changes

Cohort / File(s)	Summary
Coverage Configuration .codecov.yml	Added 24 lines of ignore patterns to exclude state transition action modules (token, document, base), their v0 submodules, transformer.rs files, transition action type enums, and identity/contract/system subtree module and transformer files from code coverage tracking.

Closing — excluding boilerplate from coverage just hides the metric without adding value. The real fix is either testing through integration paths or generating these with derive macros.
