chore(todo): complete feature suggestions TODO and queue individual tasks

- Update CI workflow runner from ubuntu-latest to ubuntu-gitea for auto-complete-todo.
- Move 3-new-feature-suggestions.md to completed/.
- Create queued TODOs for testgen, changelog, and profile features.

+# 3 New AI-Enhanced Feature Suggestions for Grokkit
+
+These suggestions build on existing CLI strengths (chat/edit/lint/agent) to further streamline Go development workflows.
+
+## 1. `grokkit testgen [path...]`
+**Description**: Generate comprehensive unit tests for Go files/packages using AI analysis of source code.
+
+**Benefits**:
+- Boost test coverage from current ~72% baseline automatically.
+- Enforces modern table-driven tests with `t.Parallel()` matching codebase style (e.g., `internal/version/version_test.go`).
+
+**High-level implementation**:
+- Extract funcs/structs via `go/ast` or prompt with code snippets.
+- Prompt Grok: "Generate table-driven tests for this Go code."
+- Output `*_test.go`, create `.bak`, preview/apply like `edit`.
+- Verify: `go test -v ./...` post-generation.
+
+**CLI example**:
+```
+grokkit testgen internal/grok/client.go
+```
+
+## 2. `grokkit changelog`
+**Description**: AI-generated CHANGELOG.md updates from git history (commits/tags).
+
+**Benefits**:
+- Automates semantic release notes (feat/fix/docs/etc.).
+- Integrates with TODO workflow for release PRs.
+
+**High-level implementation**:
+- Fetch `git log --pretty=format:%s%n%b --since=<last-tag>`.
+- Prompt Grok: "Categorize into CHANGELOG sections."
+- Append/update `CHANGELOG.md`, preview/commit.
+
+**CLI example**:
+```
+grokkit changelog --since=v0.1.3
+grokkit changelog --commit  # Stage + grokkit commit
+```
+
+## 3. `grokkit profile`
+**Description**: Run Go benchmarks/pprof, get AI-suggested performance optimizations.
+
+**Benefits**:
+- Tune CLI hotspots (e.g., API streaming, git subprocesses).
+- Proactive perf improvements without manual profiling.
+
+**High-level implementation**:
+- `go test -bench=. -cpuprofile=prof.out ./cmd`.
+- Parse pprof data (stdlib `pprof` or text), prompt Grok: "Optimize these hotspots."
+- Suggest edits via `agent` or `edit --preview`.
+
+**CLI example**:
+```
+grokkit profile ./cmd/agent.go
+# Outputs: hotspots, suggestions, optional auto-fixes
+```
+
+These features align with minimal deps, modern Go, and existing patterns (Cobra cmds, grok client, git integration).
