Update @github/copilot to 1.0.71 (#1998)

* Update @github/copilot to 1.0.71

- Updated nodejs and test harness dependencies
- Re-ran code generators
- Formatted generated code

* Route Python hooks.invoke through generated client-global handler

CLI 1.0.71 promoted hooks.invoke to a client-global RPC method with a
generated HooksHandler interface. The handwritten SDK still registered its
own hooks.invoke handler, which only avoided colliding with the generated
one because global handlers were skipped when no LLM/telemetry adapter was
set.

Make the wiring intentional: add _HooksAdapter implementing the generated
HooksHandler protocol (routing HookInvokeRequest.sessionId to the matching
session's dispatcher), always register the client-global handlers with the
hooks adapter, and remove the redundant handwritten hooks.invoke
registrations and dead client-level handler.

* Route Node hooks.invoke through generated client-global handler

CLI 1.0.71 promoted hooks.invoke to a client-global RPC method with a
generated HooksHandler interface. The handwritten SDK registered its own
hooks.invoke handler on the connection, which the generated
registerClientGlobalApiHandlers then shadowed with an unwired handler that
threw "No hooks client-global handler registered" — so hooks never fired.

Wire the existing handleHooksInvoke routing into the generated
clientGlobalHandlers.hooks slot and drop the redundant handwritten
connection.onRequest("hooks.invoke") registration. Behavior is unchanged;
the dispatcher and its payload validation are reused as-is.

* Route Go hooks.invoke through generated client-global handler

CLI 1.0.71 promoted hooks.invoke to a client-global RPC method whose
generated registration installs a hooks.invoke handler that rejects all
invocations unless the Hooks slot is populated. Whenever an LLM inference
or telemetry adapter was configured, that generated handler overrode the
handwritten hooks.invoke registration and hooks stopped firing (e.g. the
sub-agent hook test).

Always register the client-global handlers with a hooksAdapter that
delegates to the existing per-session dispatcher, and drop the redundant
handwritten hooks.invoke registration.

* Fix Rust hook input deserialization for float timestamps

The Copilot CLI serializes hook input `timestamp` as a JSON float
(e.g. `1784203878038.0`). Rust's hand-authored hook input structs typed
`timestamp` as `i64`, so `serde_json::from_value` rejected the float,
`dispatch_hook` returned an error, and the session handler fell back to
an empty `{ "output": {} }` response. Hooks therefore never fired: e.g. a
preToolUse deny was dropped, the CLI executed the tool, and the replayed
conversation diverged ("No cached response" -> 500).

Other SDKs tolerate this incidentally (Go decodes `input` into `any` and
re-marshals, dropping the `.0`); Rust decodes strictly. Type the hook
input `timestamp` fields as `f64` to match the shape the runtime sends.

* Fix .NET build break and float hook timestamps for hooks.invoke

CLI 1.0.71 promoted hooks.invoke to an internal client-global RPC method.
The C# codegen still emitted its internal request/result DTOs behind a public
IHooksHandler surface, producing CS0050/CS0051 inconsistent-accessibility
errors that broke the entire .NET build. It also registered a second, unwired
hooks.invoke handler that would shadow the working handwritten one.

Filter internal client-global and client-session methods in the C# code
generator so no generated interface, handler property, or RPC registration is
emitted for internal methods like hooks.invoke. The handwritten
SetLocalRpcMethod(hooks.invoke, ...) registration continues to serve hooks.
This mirrors, for .NET's static typing, the routing fixes already applied to
Node, Python, and Go.

Also tolerate hook timestamp epoch milliseconds encoded as either JSON
integers or floats in UnixMillisecondsDateTimeOffsetConverter, covering the
CLI 1.0.71 float serialization (matching the Rust fix).
