feat(review): add configurable approval prompts (#561)

* feat(review): add configurable approval prompts

Let users override the agent message Plannotator sends after approving a code review. Keep the existing behavior by default while supporting runtime-specific overrides in ~/.plannotator/config.json.

* fix(shared): export prompts helper

Expose the new shared prompts module through @plannotator/shared so Bun can resolve it during hook builds and CI.

* fix: add Gemini CLI to agent origin detection chain

Gemini CLI sets GEMINI_CLI=1 in the environment. Add it to the
detectedOrigin chain so runtime-specific prompt overrides work
on all paths (review, annotate, plan), not just plan review.

For provenance purposes, this commit was AI assisted.

 ## Submitting feedback
 
 - **Send Feedback** formats your annotations and sends them to the agent
-- **Approve** sends "LGTM" to the agent, indicating the changes look good
+- **Approve** sends a review-approval prompt to the agent. By default this says no changes were requested, and you can override it in `~/.plannotator/config.json`.
 
 After submission, the agent receives your feedback and can act on it, whether that's fixing issues, explaining decisions, or making the requested changes.
 
+### Customizing the approval prompt
+
+You can override the approval prompt in `~/.plannotator/config.json`.
+
+```json
+{
+  "prompts": {
+    "review": {
+      "approved": "# Code Review\n\nCommit these changes now.",
+      "runtimes": {
+        "opencode": {

+
+Resolution order:
+
+1. `prompts.review.runtimes.<runtime>.approved`
+2. `prompts.review.approved`
+3. Plannotator's built-in default
+
+Runtime keys use Plannotator's runtime identifiers. For code review, the current values are `claude-code`, `opencode`, `copilot-cli`, `pi`, and `codex`.

 Approved and denied plans are saved to `~/.plannotator/plans/` by default. You can change the save directory or disable saving in the Plannotator UI settings (gear icon).
 
+## Config file
+
+Plannotator also reads `~/.plannotator/config.json` for persistent settings and feature-specific overrides.
+
+For example, code review approval prompts can be customized there. See the code review docs for the prompt shape and supported runtime keys.

 ## Remote mode
 
 When working over SSH, in a devcontainer, or in Docker, set `PLANNOTATOR_REMOTE=1` (or `true`) and `PLANNOTATOR_PORT` to a port you'll forward. Set `PLANNOTATOR_REMOTE=0` / `false` if you need to force local behavior even when SSH env vars are present. See the [remote & devcontainers guide](/docs/guides/remote-and-devcontainers/) for setup instructions.
