## What changed
- Normalize both tool invocations and subscription filters before matching them.
- Treat missing and empty namespaces as aliases for the `functions` namespace while preserving the namespace reported with each invocation.
## Testing
- Add a gRPC service test covering missing, empty, and explicit default namespaces on both sides of a filtered subscription.

## What changed
Allow the gRPC code-mode host to register more than
`MAX_IN_FLIGHT_REQUESTS` open sessions. Existing limits on in-flight
requests, control requests, and active cells remain unchanged.

## Why
Code-mode tool failure messages larger than 64 KiB were truncated before they
reached the host.
## What changed
- Remove the tool error size limit from the gRPC protocol and host validation.
- Forward failed tool completion messages without truncation.
## Testing
- Verify that a multibyte error larger than 64 KiB is preserved exactly.

## What changed
Stop rejecting code-mode execute requests solely because `enabled_tools`
contains more than 1,024 definitions. Continue validating each tool definition
while converting the request.

## What changed
- Subscribe each gRPC code-mode session to nested tool calls and forward tool and notification callbacks to its delegate.
- Complete tool calls through the host while bounding oversized results and errors.
- Track callback ownership and cancellation so completed cells drain notifications, terminated cells cancel them, and shutdown revokes outstanding work.
- Validate callback identifiers, cell ownership, enabled tools, and pending callback limits without serializing independent callbacks or sessions.
## Testing
- Add integration and state tests for callback forwarding, completion ordering, cancellation, malformed callbacks, delegate panics, oversized results, and concurrent work.

## What changed
- Add `GrpcCodeModeSessionProvider` for opening code-mode sessions over HTTP/2 or an existing `tonic` channel.
- Support execution, waiting, termination, per-session limits, cell-closure callbacks, and graceful shutdown over the gRPC protocol.
- Bound transport waits and error messages, validate host identifiers and responses, and clean up abandoned executions and observers.
## Testing
- Add end-to-end TCP tests covering session persistence, cancellation, concurrent waits, shutdown, cell cleanup, and independent yield limits.
- Add unit coverage for protocol conversion, deadlines, and session lifecycle state.

## What changed
- Send notification events without waiting for client acknowledgment, so an
unacknowledged notification no longer delays cell completion.
- Keep the notification acknowledgment RPC as a compatibility no-op after
validating the session and notification ID.
- Remove pending-notification tracking and cancellation events from the gRPC
session routing path.
## Testing
- Verify that a cell completes after emitting an unacknowledged notification
and that a later acknowledgment is still accepted.

## What changed
- Export `GrpcCodeModeHost` as a transport-independent implementation of the
code-mode gRPC API.
- Support leased sessions, execution and wait lifecycle operations, filtered
nested tool-call subscriptions, tool completions, and notification
acknowledgements.
- Share host-wide request and active-cell limits across the existing and gRPC
transports, and bound identifiers, metadata, subscriptions, and pending
callbacks.
## Testing
- Add coverage for request conversion, ordered callback routing, cancellation,
session cleanup, backpressure, malformed input, and resource-limit handling.
