feat(ultraplan-local): v1.6.0 — /ultraresearch-local deep research command

Add /ultraresearch-local for structured research combining local codebase
analysis with external knowledge via parallel agent swarms. Produces research
briefs with triangulation, confidence ratings, and source quality assessment.

New command: /ultraresearch-local with modes --quick, --local, --external, --fg.
New agents: research-orchestrator (opus), docs-researcher, community-researcher,
security-researcher, contrarian-researcher, gemini-bridge (all sonnet).
New template: research-brief-template.md.

Integration: --research flag in /ultraplan-local accepts pre-built research
briefs (up to 3), enriches the interview and exploration phases. Planning
orchestrator cross-references brief findings during synthesis.

Design principle: Context Engineering — right information to right agent at
right time. Research briefs are structured artifacts in the pipeline:
ultraresearch → brief → ultraplan --research → plan → ultraexecute.

+
+## Key Settings
+
+### model
+
+Default model for this project/user:
+
+```json
+{
+  "model": "sonnet"  // or "opus", "haiku"
+}
+```
+
+### permissions
+
+Control tool access:
+
+```json
+{
+  "permissions": {
+    "allow": [
+      "Read",
+      "Write",
+      "Bash(npm *)",
+      "Bash(git *)",
+      "Task"
+    ],
+    "deny": [
+      "Bash(rm -rf *)",
+      "Bash(sudo *)"
+    ]
+  }
+}
+```
+
+Patterns support wildcards:
+- `*` matches any characters
+- `Bash(npm*)` matches `npm install`, `npm test`, etc.
+
+### env
+
+Environment variables:
+
+```json
+{
+  "env": {
+    "NODE_ENV": "development",
+    "DEBUG": "true"
+  }
+}
+```
+
+### hooks
+
+Event-driven automation:
+
+```json
+{
+  "hooks": {
+    "PreToolUse": [
+      {
+        "matcher": "Bash",
+        "command": "echo 'About to run bash'"
+      }
+    ]
+  }
+}
+```
+
+## Merging Behavior
+
+When multiple settings files exist:
+- Objects are merged recursively
+- Arrays are replaced, not merged
+- Higher precedence wins for conflicts
