Update agent roles and AGENTS.md for open-coordinator and open-memory plugins

Replace outdated worktree_make/worktree_mode/worktree_overview/worktree_cleanup
API references with the new worktree({action, args}) dispatch pattern from
open-coordinator. Add worktree notify tool for implementation/code-review/POC
agents to communicate back to coordinator. Fix stale alkhub_ts paths. Add
open-memory plugin awareness (memory, memory_compact) to AGENTS.md and agent
specs. Update sdd_process.md coordinator section accordingly.

+## The `worktree` Tool (Implementation Agent)
+
+As a spawned implementation agent, you have access to a limited set of worktree operations:
+
+```text
+worktree({action: "current"})                              → Show your worktree mapping
+worktree({action: "notify", args: {message: "...", level: "info"}})  → Report to coordinator
+worktree({action: "status"})                                 → Show worktree git status
+worktree({action: "help"})                                    → Show available operations
+```
+
+### Communicating with the Coordinator
+
+Use `worktree({action: "notify", ...})` to report progress and issues:
+
+```text
+worktree({action: "notify", args: {message: "Tests passing, starting implementation", level: "info"}})
+worktree({action: "notify", args: {message: "Blocked: missing dependency", level: "blocking"}})
+worktree({action: "notify", args: {message: "Task completed", level: "info"}})
+```
+
+- **info**: Progress updates, completions
+- **blocking**: You're stuck, need coordinator intervention (triggers Safe Exit)

+OpenCode spawns a NEW shell per command. The open-coordinator plugin auto-injects `workdir` for bash commands when the session is mapped to a worktree. This means:
 
 ```bash
-# ❌ WRONG
-deno test -A
-cd /worktrees/... && deno test -A
+# ✅ CORRECT — workdir is auto-injected
+npm test
 
-# ✅ CORRECT
-bash({ command: "deno test -A", workdir: "/workspace/@alkdev/alkhub_ts/.worktrees/feat/<task-id>/" })
+# ✅ ALSO CORRECT — explicit workdir still works
+bash({ command: "npm test", workdir: "/path/to/worktree" })
 ```
 
+**Do NOT use `cd` in commands** — it doesn't persist and the plugin handles routing.

+## Context & Memory (via @alkdev/open-memory)
+
+When available, use memory tools to manage your context:
+
+- `memory({tool: "context"})` — check context window usage, especially during long implementations
+- `memory({tool: "messages", args: {sessionId: "..."}})` — review previous assistant messages if you lose track
+- `memory({tool: "search", args: {query: "..."}})` — search past conversations for relevant context
+- `memory_compact()` — compact at natural breakpoints (e.g., after completing a subtask) when context is above 80%
+
+This is especially important for complex tasks that span many file operations.
+
 ## Key Principles
 
 1. **Read first** - understand before implementing
 2. **Verify before completing** - all criteria met
 3. **Safe exit is okay** - better to block than force failures
 4. **Minimal changes** - implement exactly what's needed
