When the backend emits RunErrorEvent via the AG-UI protocol, several
components did not handle it:
- ProxiedCopilotRuntimeAgent: isRunning stayed true, causing
data-copilot-running to never transition to false (infinite spinner)
- StateManager: activeRun entries were never cleaned up, runFinished
flag never set (stale state on subsequent runs)
- Angular CopilotKitAgent: same isRunning bug as the proxy agent
- useAgentNodeName: node name stuck at last step instead of "end"
onRunErrorEvent is distinct from onRunFailed — the former handles
protocol-level RUN_ERROR events from the backend, the latter handles
local exceptions (network errors, deserialization failures).
- Fix fetchRuntimeInfoAutoDetect in agent.ts to use 2xx-only check
(was checking only 404/405, now aligns with agent-registry.ts)
- Remove duplicate JSDoc block on fetchRuntimeInfoAutoDetect
- Add 7 edge case tests: 500/403/405/network-error/both-fail scenarios
- Add 4 tests for useSingleEndpoint->runtimeTransport ternary mapping
- Update Angular test stubs to use "auto" default (was "rest")

Instead of requiring users to explicitly set transport: "single", the
client now auto-detects the transport mode by trying REST (GET /info)
first and falling back to single-endpoint (POST with { method: "info" })
if the REST probe returns 404/405 or fails. The explicit flag is kept
for backward compatibility.

Replace eslint and prettier with oxlint and oxfmt for faster linting
and formatting across the monorepo. Remove all eslint and prettier
configs, dependencies, and related packages. Add .oxlintrc.json and
.oxfmtrc.json for the new tooling. Update CI workflows and lefthook
hooks accordingly. Reformat codebase with oxfmt.

Flatten all packages from packages/v1/* and packages/v2/* into packages/* —
every package now lives directly under the @copilotkit/ scope with no v1/v2
subdirectories.
- Move all v1 packages (react-core, react-ui, runtime, shared, etc.) from
packages/v1/* to packages/*
- Absorb v2 react code into packages/react-core/src/v2/ (exported via /v2 subpath)
- Absorb v2 agent code into packages/runtime/src/agent/ (exported via /v2 subpath)
- Move v2 packages (core, angular, demo-agents, etc.) to packages/*
- Replace all @copilotkitnext/* imports with @copilotkit/* equivalents
- Keep @copilotkitnext/angular as the sole exception (angular remains on next)
- Update CI workflows, renovate config, release scripts for flat structure
- No public API surface changes — all exports fields are preserved
