feat: default requests to a 30 second timeout

[razor-x]

Part of a four-SDK change adding a default HTTP timeout (javascript-http, ruby, python).

Problem

Unlike the other three SDKs, this one already had a timeout — but 100 seconds, an openapi-generator leftover rather than a deliberate choice, and far longer than the API's own request timeout.

Changes

• Lower the default to 30 seconds behind a named SeamRequestConfiguration.DefaultTimeout constant, so the value reads as a decision instead of a generator artifact.
• Add a timeout parameter, in milliseconds, to SeamClient (and the obsolete Seam subclass) so it can be set per client.
• The per-client value takes precedence over configuration.Timeout in both Exec and ExecAsync; the configuration remains available for setting the default globally.

var seam = new SeamClient(apiToken: "YOUR_API_KEY", timeout: 60000);

// Or globally
GlobalSeamRequestConfiguration.Instance.Timeout = 60000;

Files under output/csharp/src/Seam/Client/ are checked in and hand-maintained rather than generated — the codegen only produces Api/ and Model/ — so no regeneration is needed.

Behavior change

Requests that previously ran between 30 and 100 seconds will now fail. The timeout parameter and the global configuration are both opt-outs.

Overload resolution

Both SeamClient constructors gain an optional int? timeout = null. This is source-compatible for every sensible call. The one call whose binding changes is new SeamClient(someString, null), which now resolves to (apiToken, timeout: null) rather than (basePath, apiToken: null) — code that previously threw ArgumentException("apiToken cannot be empty") at runtime. Adding an optional parameter is a binary-breaking change, so consumers recompile against the new package as usual.

Testing

Unverified — CI is the first real run. There is no .NET toolchain in my environment, so I could not build, test, or run csharpier on this branch. output/csharp/src/Seam.Test/Client/TimeoutTests.cs is new and covers the default constant, configuration defaults, merge precedence, and construction with an explicit timeout. Please expect a formatting fixup if csharpier disagrees with my hand-formatting.
