[autodev] Update configuration and documentation for cycle-1

- Enhanced `.env.example` with detailed CMake build flags and replay-mode strategy flags for development and CI environments.
- Updated `.gitignore` to include a new deploy rollback bookmark.
- Revised `_docs/_autodev_state.md` to reflect the current task status and steps.
- Added new lessons to `_docs/LESSONS.md` regarding testing and architectural improvements.
- Documented changes in `_docs/02_document/deployment/ci_cd_pipeline.md` to reflect the relaxed OpenCV version pin.
- Updated test data documentation in `_docs/02_document/tests/test-data.md` to clarify fixture usage and paths.

This commit continues the cycle-1 documentation sync and addresses various configuration updates for improved clarity and functionality.

+# Cycle-1 trigger: manual-only.
+#
+# Rationale (per _docs/04_deploy/ci_cd_pipeline.md → Decision Record):
+#   The Tier-1 e2e harness (docker-compose.test.yml + tests/e2e/Dockerfile)
+#   is heavy: TensorRT-class pytorch fp16, gtsam, Postgres 16, and the
+#   Derkachi replay clip. It is shipped opt-in until per-run wall-clock on
+#   the colocated arm64 Jetson agent is characterised.
+#
+# Flip-back (cycle-2 polish item #1 in _docs/04_deploy/ci_cd_pipeline.md):
+#   1. Replace `event: [manual]` with `event: [push, pull_request, manual]`
+#      below.
+#   2. Add `depends_on: [01-test]` to .woodpecker/02-build-push.yml.
