Michal a869f77070 merge: AgentProject membership — the junction is now load-bearing
Merges feat/agent-project-membership (task 166/152). An agent can finally join
many projects: membership routes, per-membership role and optional brain
override, chat resolving context from the membership, and CLI attach-agent /
detach-agent / get memberships. The legacy Agent.projectId fallback is kept for
this release as the schema comment promises.

Conflict resolved in main.ts: that branch added its RBAC case to
mapUrlToPermission inline, while this branch had extracted the function to
middleware/url-permission.ts so it could be tested. Kept the extraction and
ported the case into it — joining a team is `edit:agents:<name>`, not
`create:agents`, which is the authority to mint a whole agent.

Also fixes something the extraction makes possible. security.test.ts contained a
hand-copied reproduction of mapUrlToPermission, because main.ts self-invokes
main() and nothing in it was importable. A security test asserting against a
copy stops testing the system the moment the real one changes, and this copy had
already drifted. It now imports the real function; all 18 assertions still pass,
against the code that actually runs.

Local: build clean, workspace 2550 passed, lint unchanged at 794 errors.

# Task ID: 84
**Title:** Implement Section Drill-Down for Tool Results
**Status:** done
**Dependencies:** 82 ✓
**Priority:** medium
**Description:** Extend tool result handling to support _section parameter for drilling into specific sections of large tool responses.
**Details:**
Modify tool call handling in `src/mcplocal/src/router.ts`:
```typescript
// When processing tool calls
if (args._section) {
const sectionId = args._section;
delete args._section; // Don't pass to upstream
// Check cache for previous full result
const cacheKey = `tool:${serverName}/${toolName}:${JSON.stringify(args)}`;
const cachedResult = this.toolResultCache.get(cacheKey);
if (cachedResult?.sections) {
const section = findSection(cachedResult.sections, sectionId);
if (section) {
return { content: [{ type: 'text', text: section.content }] };
}
}
// If no cache, make the full call and process, then serve section
}
// After receiving tool result, process through pipeline
const processed = await this.processContent(result, 'toolResult', `${serverName}/${toolName}`, sessionId);
if (processed.sections) {
this.toolResultCache.set(cacheKey, processed);
}
```
Add a toolResultCache Map with appropriate TTL.
**Test Strategy:**
Integration tests: large tool result gets processed into sections, _section parameter returns specific section, _section removed before upstream call, cache hit serves from cache, cache miss processes and caches.
