Branch: fix/sandbox-manager-spec-contradiction-atomicity
Commit Message: fix(sandbox): resolve spec contradiction between atomicity (line 45938) and partial apply (line 19193)
Milestone: (none — backlog)
Parent Epic: #394

Bug Description

SandboxManager.commit_all() in src/cleveragents/infrastructure/sandbox/manager.py implements an all-or-nothing atomic commit (if any sandbox fails, all previously committed sandboxes are rolled back). However, the specification contains a contradiction:

Spec line 45938: Requires atomicity ("all or none") for the Apply phase
Spec line 19193: States "If any sandbox Apply fails, others may still succeed (partial apply)"

The code currently implements the atomicity requirement from line 45938 and documents this contradiction in a .. note:: docstring comment. This unresolved contradiction means the behavior is not clearly specified and could lead to incorrect implementations.

Code location: src/cleveragents/infrastructure/sandbox/manager.py, commit_all() method docstring:

.. 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.

Expected behavior:
The specification should be internally consistent. Either:

The Apply phase is atomic (all-or-nothing) — spec line 19193 should be updated to remove the "partial apply" language
The Apply phase allows partial apply — spec line 45938 should be updated to remove the atomicity requirement, and commit_all() should be updated to not roll back on failure

Actual behavior:
The code implements atomicity (option 1) but the spec contradiction remains unresolved. This creates ambiguity for future implementors and reviewers.

Steps to reproduce:

Read src/cleveragents/infrastructure/sandbox/manager.py, commit_all() docstring
Observe the .. note:: Specification contradiction section
Read docs/specification.md line 45938 (atomicity requirement)
Read docs/specification.md line 19193 (partial apply statement)
Note the contradiction

Fix approach:

Determine the correct intended behavior (atomic vs partial apply)
Update docs/specification.md to resolve the contradiction
If atomicity is correct: update line 19193 to align with line 45938
If partial apply is correct: update commit_all() to not roll back on failure and update line 45938

Subtasks

Review spec lines 45938 and 19193 to determine intended behavior
Update docs/specification.md to resolve the contradiction
Update SandboxManager.commit_all() docstring to remove the contradiction note
If behavior changes, update implementation and tests accordingly
Verify all nox quality gates pass

Definition of Done

docs/specification.md is internally consistent regarding Apply phase atomicity
SandboxManager.commit_all() docstring no longer references a spec contradiction
All nox stages pass
Coverage >= 97%

Backlog note: This issue was discovered during autonomous operation
on milestone v3.6.0. It does not block milestone completion and has been
placed in the backlog for human review and future milestone assignment.
