feat: SDK update for version 26.0.0-rc.2

[ChiragAgg5k]

This PR contains updates to the SDK for version 26.0.0-rc.2.

What's Changed

• Added: graphql query and graphql mutation accept a raw GraphQL document at --query
• Added: init skill takes --all, --skill, --agent, and --method for headless installs
• Added: --code on functions and sites create-deployment accepts a source directory
• Fixed: Requests no longer fail at a ten second deadline, so large uploads complete
• Fixed: --self-signed reaches service commands instead of being dropped before the request
• Fixed: A timed out mutation reports an unknown outcome instead of an ordinary failure
• Fixed: --documents, --rows, --columns, --attributes, --indexes, and --operations parse each value as JSON
• Updated: list-specifications documents that --type defaults to runtimes

Greptile Summary

This release-candidate update expands headless skill installation, raw GraphQL input, and source-directory deployments while updating generated service argument conversion and HTTP timeout handling.

• Adds JSON-aware conversion for generated array parameters and GraphQL request envelopes.
• Packages function and site source directories before deployment.
• Shares phase-bounded and self-signed-aware HTTP transport behavior with generated SDK commands.
• Classifies timed-out mutating operations as having an unknown outcome.
• Updates release metadata and installer versions to 26.0.0-rc.2.

Confidence Score: 4/5

The PR appears safe to merge, with one non-blocking diagnostic issue in the GraphQL query timeout path.

The changed GraphQL query handler labels a read-only query timeout as an uncertain mutation, so affected users receive misleading duplicate-change recovery guidance; no blocking runtime, data-integrity, or security failure remains.

Files Needing Attention: internal/cmd/services/graphql.go

Important Files Changed

Filename	Overview
internal/sdk/capture.go	Adds mutation-timeout classification and replaces the SDK-wide deadline with the shared phase-bounded recording transport.
internal/sdk/sdk.go	Routes generated SDK clients through the shared HTTP policy so self-signed settings and long uploads work through response capture.
internal/client/client.go	Introduces a shared HTTP client factory with optional certificate-verification bypass and response-header timeout boundaries.
internal/app/inputfile.go	Adds temporary packaging and cleanup for deployment source directories while preserving direct archive uploads.
internal/app/convert.go	Adds raw GraphQL document/envelope conversion and JSON decoding for repeatable generated-service arguments.
internal/cmd/initskill.go	Adds explicit skill, agent, and installation-method selection for non-interactive installation.
internal/cmd/services/graphql.go	Accepts raw GraphQL documents but misclassifies query timeouts as uncertain mutations because the endpoint uses POST.
internal/cmd/services/functions.go	Allows deployment code to be supplied as either an archive or source directory with correctly deferred cleanup.
internal/cmd/services/sites.go	Mirrors source-directory deployment support for sites.
internal/cmd/services/databases.go	Decodes JSON-valued generated parameters and consistently applies shared timeout error handling.
internal/cmd/services/tablesdb.go	Decodes JSON-valued row, column, index, and operation arguments before SDK calls.

Prompt To Fix All With AI

### Issue 1
internal/cmd/services/graphql.go:42-45
**Query timeout marked as mutation**

When a read-only GraphQL query times out, `WrapMutationError("POST", err)` reports an unknown mutation outcome and warns about duplicate changes. Return the ordinary timeout for this query path so users receive relevant retry guidance.

```suggestion
			result, err := service.Query(queryValue)
			if err != nil {
				return err
			}
```
