Refine coding standards and testing guidelines

- Updated the coding rule descriptions to emphasize readability, meaningful comments, and test verification.
- Revised guidelines to clarify the importance of avoiding boilerplate while maintaining readability.
- Enhanced the testing rules to set a minimum coverage threshold of 75% for business logic and specified criteria for test scenarios.
- Introduced a mechanism for handling skipped tests, categorizing them as legitimate or illegitimate, and outlined resolution steps.

These changes aim to improve code quality, maintainability, and testing effectiveness.

+Bounded auto-fix loop — only applies to **mechanical** findings. Critical and Security findings are never auto-fixed.
 
-1. If verdict is **PASS** or **PASS_WITH_WARNINGS**: show findings as info, continue automatically to step 11
-2. If verdict is **FAIL** (attempt 1 or 2):
-   - Parse the code review findings (Critical and High severity items)
-   - For each finding, attempt an automated fix using the finding's location, description, and suggestion
-   - Re-run `/code-review` on the modified files
-   - If now PASS or PASS_WITH_WARNINGS → continue to step 11
-   - If still FAIL → increment retry counter, repeat from (2) up to max 2 attempts
-3. If still **FAIL** after 2 auto-fix attempts: present all findings to user (**BLOCKING**). User must confirm fixes or accept before proceeding.

+2. If verdict is **FAIL**:
+   - Partition findings into auto-fix-eligible and escalate (using the matrix above)
+   - For eligible findings, attempt fixes using location/description/suggestion, then re-run `/code-review` on modified files (max 2 rounds)
+   - If all remaining findings are auto-fix-eligible and re-review now passes → continue to step 11
+   - If any non-eligible finding exists at any point → stop auto-fixing, present the full list to the user (**BLOCKING**)
+3. User must explicitly approve each non-auto-fix finding (accept, request manual fix, mark as out-of-scope) before proceeding.
+
+Track `auto_fix_attempts` and `escalated_findings` in the batch report for retrospective analysis.

+### 11. Commit (and optionally Push)
 
 - After user confirms the batch (explicitly for FAIL, implicitly for PASS/PASS_WITH_WARNINGS):
   - `git add` all changed files from the batch
   - `git commit` with a message that includes ALL task IDs (tracker IDs or numeric prefixes) of tasks implemented in the batch, followed by a summary of what was implemented. Format: `[TASK-ID-1] [TASK-ID-2] ... Summary of changes`
-  - `git push` to the remote branch
+  - Ask the user whether to push to remote, unless the user previously opted into auto-push for this session
