feat(plugins): add TimeNow function to SchedulerService (#4337)
* feat: add TimeNow function to SchedulerService plugin

Added new TimeNow RPC method to the SchedulerService host service that returns
the current time in two formats: RFC3339Nano string and Unix milliseconds int64.
This provides plugins with a standardized way to get current time information
from the host system.

The implementation includes:
- TimeNowRequest/TimeNowResponse protobuf message definitions
- Go host service implementation using time.Now()
- Complete test coverage with format validation
- Generated WASM interface code for plugin communication

* feat: add LocalTimeZone field to TimeNow response

Added LocalTimeZone field to TimeNowResponse message in the SchedulerService
plugin host service. This field contains the server's local timezone name
(e.g., 'America/New_York', 'UTC') providing plugins with timezone context
alongside the existing RFC3339Nano and Unix milliseconds timestamps.

The implementation includes:
- New local_time_zone protobuf field definition
- Go implementation using time.Now().Location().String()
- Updated test coverage with timezone validation
- Generated protobuf serialization/deserialization code

* docs: update plugin README with TimeNow function documentation

Updated the plugins README.md to document the new TimeNow function in the
SchedulerService. The documentation includes detailed descriptions of the
three return formats (RFC3339Nano, UnixMilli, LocalTimeZone), practical
use cases, and a comprehensive Go code example showing how plugins can
access current time information for logging, calculations, and timezone-aware
operations.

* docs: remove wrong comment from InitRequest

* fix: add missing TimeNow method to namedSchedulerService

Added TimeNow method implementation to namedSchedulerService struct to satisfy the scheduler.SchedulerService interface contract. This method was recently added to the interface but the namedSchedulerService wrapper was not updated, causing compilation failures in plugin tests. The implementation is a simple pass-through to the underlying scheduler service since TimeNow doesn't require any special handling for named callbacks.
