fix: plugin event shape mismatches, nav highlight bug, and README update

- Fix session.created/deleted reading props.info.id instead of props.id
- Fix session.diff reading FileDiff[] array instead of string
- Fix file.edited reading props.file instead of props.filePath
- Add auto-session creation fallback from tool/chat hooks
- Add flushSession() for intermediate trace sends on session.idle
- Fix dashboard nav: /dashboard exact match prevents false active state
- Update README with TypeScript SDK and OpenCode plugin sections

+## OpenCode Plugin
+
+Trace your [OpenCode](https://opencode.ai) coding agent sessions automatically.
+
+```bash
+npm install -g opencode-agentlens
+```
+
+Add to your `opencode.json`:
+
+```json
+{
+  "plugin": ["opencode-agentlens"]
+}
+```
+
+Set environment variables:
+
+```bash
+export AGENTLENS_API_KEY="your-key"
+export AGENTLENS_ENDPOINT="https://agentlens.vectry.tech"
+```
+
+Every coding session automatically captures tool calls, LLM interactions, file edits, and permission flows.
+
+## TypeScript SDK
+
+```bash
+npm install agentlens-sdk
+```
+
+```typescript
+import { init, TraceBuilder, SpanType, SpanStatus } from "agentlens-sdk";
+
+init({ apiKey: "your-key", endpoint: "https://agentlens.vectry.tech" });
+
+const trace = new TraceBuilder("my-agent-task", {
+  tags: ["production"],
+});
+
+trace.addSpan({
+  name: "tool-call",
+  type: SpanType.TOOL_CALL,
