Errors.fs SdkError carries a doc block describing the exception

[nficano]

Category: docs Severity: minor
Location: src/Arcp.Core/Errors.fs:92-102

What

Lines 92-94 describe ArcpException but sit above SdkError. The exception-form description is then repeated correctly at lines 100-101. The misplaced doc will surface in tooltips for SdkError.

Evidence

/// Exception form for C# interop and for fatal paths in F# where
/// the spec-canonical surface is "throw with code". Carries the
/// underlying `ARCPError`.
/// Convenience alias for `ARCPError`. The protocol uses "ARCP"
/// all-caps, so the spec-named type is `ARCPError`; `SdkError`
/// is the F#-conventional name for callers who prefer it.
type SdkError = ARCPError

/// Exception form of `ARCPError` for C# callers and for paths
/// where the spec-canonical surface is "throw with code".
type ArcpException(error: ARCPError, ?inner: exn) =

Proposed fix

Delete the stray doc block at lines 92-94 (the alias doc at 95-97 is the correct one) and keep the doc at lines 100-101 on ArcpException.

Acceptance criteria

• IDE tooltip for SdkError shows only the alias description; ArcpException shows only the exception description.
