fix(repo): keep the log's history readable when the data is a folder of a bigger repo (0.4.10)

[GeiserX]

The household's data is moving into one repository shared with another bot, with each bot's data in its own folder. Pointed at a folder like that, this bot broke its own log:

• git show <rev>:cycle/log.jsonl looks for the path from the repository root, so it found no log at any revision. Every check-in commit then listed every day of the log instead of the days that changed.
• /deshacer on a pushed check-in found no log in the parent commit and ran git rm on the whole log.
• /deshacer only checked HEAD. Once the other folder's writer had a commit on top, the last check-in counted as "nothing to undo".

The fix:

• _show reads <rev>:./cycle/log.jsonl, which git resolves relative to the data directory.
• When the data directory is not the repository root, undo takes the last commit that touched it (git log -1 -- .) and restores from that commit's parent. At the root it still reads HEAD and restores from the same commit as before (<HEAD sha>~1), so nothing changes there.

Tests: a new subfolder_repo fixture builds a bare remote and two clones. The data is tracker/ and a second writer commits to doctor/. Four tests cover commit and push with a concurrent commit in the other folder, undo of the last check-in, undo under the other folder's commit, and the deleted-log conflict. On the old repo.py the first three fail (subject log: 2027-01-04, ... 2027-03-04 instead of log: 2027-03-04; undo returned every date of the log; undo returned None). The conflict test passes on both versions, as it should. Full suite: 428 passed; ruff check and format are clean.

Deploy contract: mount the whole checkout, .git included (for example at /repo), and set SCT_DATA to the folder (/repo/supercycletracker).

Summary by CodeRabbit

• Bug Fixes
  • Data directories located inside a larger Git checkout now work correctly for check-ins and undo. Updates can be synchronized alongside changes to other folders without overwriting them, and undo restores the last check-in for the data directory.
  • If the tracked log file is removed remotely, synchronization now reports a conflict and avoids pushing the local commit.
• Documentation
  • Clarified that SCT_DATA can point to a data repository checkout or a folder within one, and that the whole checkout should be mounted.

📝 Walkthrough

Documentation and repository operations now support a data directory inside a larger Git checkout. Tests cover check-in, undo, and conflict behavior when another folder in that checkout changes.

Changes: Nested Data Repository Support

Layer / File(s)	Summary
Nested data path Git behavior README.md, docs/DESIGN.md, supercycletracker/repo.py, tests/conftest.py, tests/test_repo.py, supercycletracker/__init__.py	Documentation describes nested data paths. Log retrieval and undo account for the data directory’s location within a checkout. Tests cover rebasing over a sibling-folder commit, undo behavior, and a remote log deletion conflict. The package version changes to 0.4.10.

Show the nested-checkout Docker layout.

The current command remains a valid root-checkout setup. It does not demonstrate the nested-directory behavior documented in SCT_DATA, and it still pins image 0.4.7 instead of 0.4.10. Update the example:

Suggested Docker example update

 docker run -d --name supercycletracker \
   -e TELEGRAM_BOT_TOKEN -e SCT_GIT_TOKEN -e TZ=Europe/Madrid \
-  -v "$PWD/data:/data" drumsergio/supercycletracker:0.4.7
+  -e SCT_DATA=/repo/data \
+  -v "$PWD:/repo" drumsergio/supercycletracker:0.4.10
