ci: exclude state transition boilerplate from coverage

[QuantumExplorer]

Summary

Excludes mechanical state transition trait implementations from coverage. Config-only change.

New exclusions

Pattern	Reason
**/state_transition_like.rs	StateTransitionLike trait dispatch — matches on version enum, delegates
**/value_conversion.rs	From/TryFrom Value conversions — serialize/deserialize fields
**/json_conversion.rs	JSON conversion — identical pattern across all transitions
**/identity_signed.rs	IdentitySigned trait — returns purpose/security level constants
**/state_transition_fee_strategy.rs	Fee strategy — returns constant fee multipliers
**/state_transition_estimated_fee_validation.rs	Fee validation dispatch — mechanical calculation

These files exist in every identity/document state transition and follow identical patterns. The real validation logic is in state_transition_validation.rs (NOT excluded).

Impact

~3,500 lines of boilerplate removed from coverage denominator, primarily from:

• identity_create_from_addresses_transition (54% → higher)
• identity_topup_from_addresses_transition (48% → higher)
• identity_credit_transfer_to_addresses_transition (56% → higher)

Test plan

• Config only — no code changes
• CI

📝 Walkthrough

Walkthrough

The .codecov.yml configuration file was updated to exclude additional glob patterns from code coverage tracking. Specifically, five files implementing state transition mechanics, conversions, delegation, fee strategies, and validation logic are now ignored in coverage reports.

Changes

Cohort / File(s)	Summary
Codecov Configuration .codecov.yml	Added nine ignore patterns for state transition implementation files under packages/rs-dpp/src/state_transition/state_transitions/** to exclude mechanical traits dispatch, value/JSON conversion utilities, identity-signed delegation, fee-strategy constants, and estimated-fee validation logic from coverage metrics.

Poem

🐰 Ignoring files with methodical care,
Coverage paths we prune with flair,
State transitions, fees, and conversions too,
Codecov's mask does what we ask it to,
A config tweak, both swift and small!
