Commit Message: fix: resolve specification contradiction in sandbox commit_all atomicity

Branch Name: fix/sandbox-commit-all-spec-contradiction

Background and Context

The commit_all() method in src/cleveragents/infrastructure/sandbox/manager.py (lines 245-250) contains a documented specification contradiction that creates ambiguity about the expected behavior of the apply phase.

Code Evidence:

.. note:: Specification contradiction

   Line 45938 requires atomicity ("all or none"), while line
   19193 states "partial apply" is possible.  This method
   implements the atomicity requirement from line 45938 per
   issue #925.  A spec update for line 19193 may be needed.

The Contradiction:

Line 45938 (Specification): Requires atomic commit behavior — "all or none" semantics
Line 19193 (Specification): Allows partial apply — some sandboxes can commit while others fail
Current Implementation: Enforces atomicity (follows line 45938)

This contradiction creates uncertainty about:

Whether the implementation correctly matches the intended specification
What users should expect when some sandboxes fail during commit
Whether future changes might break the contract

Expected Behavior

The specification should be unambiguous and the implementation should clearly align with it. Users should understand whether:

Atomic Mode: All sandboxes commit successfully, or the entire operation fails and is rolled back
Partial Mode: Some sandboxes can commit while others fail, with partial success reported to the caller

Acceptance Criteria

Specification lines 45938 and 19193 are reviewed and reconciled
A decision is made: atomic OR partial apply (not both)
The chosen behavior is documented in the specification
The implementation is updated to match the specification (if needed)
Code comments in commit_all() are updated to reflect the final decision
The decision is documented in an ADR or design document
All related tests verify the chosen behavior

Subtasks

Review specification lines 45938 and 19193 to understand original intent
Review issue #925 to understand the atomicity requirement context
Consult with team on intended behavior (atomic vs partial)
Document the decision in an ADR or design document
Update specification line 19193 to align with chosen behavior
Update code comments in commit_all() method
Add/update tests to verify the chosen behavior
Update any related documentation or user guides

Definition of Done

This issue is complete when:

The specification contradiction is resolved (one behavior chosen)
Both specification lines 45938 and 19193 are consistent
The implementation matches the specification
Code comments clearly explain the chosen behavior and why
Tests verify the chosen behavior
An ADR or design document explains the decision and rationale
No contradictory notes remain in the codebase
