v0.0.5: feat: support metadata merging in flag evaluation responses (#40)
## Description
Implements metadata merging per the flagd provider specification:
evaluation responses now merge flag-set metadata (root-level config
fields) with flag-level metadata, with flag metadata taking precedence
on key conflicts.
**Key Changes:**
- **Evaluation API**: Updated `evaluate_flag()` and type-specific
evaluators to accept `flag_set_metadata` parameter
- **Merge Logic**: Added `merge_metadata()` helper implementing flag
metadata priority
- **Result Coverage**: Metadata now included in all resolution paths:
- `STATIC`, `DEFAULT`, `TARGETING_MATCH`, `DISABLED`: Merged flag-set +
flag metadata
- `FLAG_NOT_FOUND`: Flag-set metadata only (best effort)
- `ERROR`: No metadata
- **Tests**: 6 new tests covering priority handling, single-source
scenarios, disabled flags, and targeting
- **Bug Fixes**: Resolved test failures from conflict resolution by
fixing missing parameters in three test functions
**Example:**
```rust
// Config with both flag-set and flag-level metadata
let config = r#"{
"version": "1.0",
"env": "prod",
"flags": {
"feature": {
"state": "ENABLED",
"variants": {"on": true, "off": false},
"defaultVariant": "on",
"metadata": {
"env": "staging", // Overrides flag-set
"owner": "team-a" // Flag-only
}
}
}
}"#;
// Result includes merged metadata:
// {"env": "staging", "owner": "team-a", "version": "1.0"}
```

## Additional Notes
All 315+ tests passing (210 lib + 21 cli + 78 integration + 6 new
metadata tests). API change is additive - new parameter added to
internal evaluation functions, all callers updated. Fixed test failures
from merge conflict resolution and applied code formatting.
