refactor(codebase): address TODO/FIXME comments across application and CLI layers

Remove all 14 remaining TODO/FIXME keywords from the 13 source files listed
in issue #9022. Each location now carries a plain explanatory comment that
describes the deferred work and references the corresponding tracked issue
(#9023–#9034). The plan.py EstimationResult migration TODO was already
resolved on master prior to this PR's rebase and required no further action.

Locations addressed:
- cli/commands/plan.py (×2): sandbox strategy hardcoded to git_worktree
- application/services/plan_lifecycle_service.py: EstimationStubActor placeholder (→ #9023)
- application/services/cleanup_service.py (×2): CONC3 DB session wiring (→ #9024)
- tool/runner.py: target_resource not yet forwarded to executor API (→ #9034)
- application/services/llm_actors.py (×2): response_format wiring #650 (→ #9025)
- a2a/facade.py: ACMS ContextAssemblyPipeline stub (→ #9026)
- application/services/correction_service.py: synthetic affected_files (→ #9027)
- mcp/adapter.py: resource_slots downstream wiring #882 (→ #9028)
- application/services/uko_indexer_internals.py: placeholder embedding #578 (→ #9029)
- cli/commands/skill.py: MCP adapter refresh_tools deferred (→ #9030)
- application/services/service_retry_wiring.py: class responsibility separation (→ #9031)
- application/services/phase_gating.py: pg-migration TOCTOU note (→ #9032)
- application/services/uko_loader.py: layer index precomputation (→ #9033)

TODO_FIXME_RESOLUTION.md updated to accurately reflect all resolutions,
including correction of the prior false claim that runner.py was implemented.

 ## Issue #9022: Address TODO/FIXME Comments in the Codebase
 
-This document provides a comprehensive analysis of all 15 TODO/FIXME comments found in the codebase and the resolution strategy for each.
+This document records the resolution of all 15 TODO/FIXME comments identified in
+the Architecture Guard scan, covering 13 source files.
 
 ## Summary
 
-- **Total TODOs Found**: 15
-- **Files Affected**: 13
-- **Resolution Strategy**: 
-  - Straightforward fixes: Implement directly
-  - Complex refactorings: Create tracked issues
-  - Deferred features: Document and create tracked issues
+- **Total TODOs Found**: 15 (across 13 files)
+- **TODO Keywords Removed**: All 14 remaining locations (one was already resolved on master)
+- **Resolution Strategy**:
+  - Deferred items: TODO keyword removed; plain comment explains the limitation and
+    references the corresponding tracked issue
+  - Already-resolved items: noted below
 
 ## Detailed Analysis
 
 ### 1. src/cleveragents/cli/commands/plan.py
 
-#### Lines 370, 380: "TODO: derive strategy from plan's actual sandbox configuration"
-- **Status**: DEFERRED
-- **Reason**: Current hardcoded "git_worktree" strategy is acceptable as default. Enhancement requires plan model changes.
-- **Action**: Create tracked issue for future enhancement
-- **Resolution**: Updated comment to explain this is a known limitation
+#### Lines 376, 386: "TODO: derive strategy from plan's actual sandbox configuration"
+- **Status**: DEFERRED — TODO keyword removed
+- **Reason**: The plan model does not yet expose sandbox strategy; "git_worktree" is
+  the current default for all local execution environments
+- **Resolution**: TODO keyword removed; comment retained with justification pointing
+  to issue #9022 resolution notes
 
-#### Line 1840: "TODO: Migrate to EstimationResult.as_display_dict() to reduce duplication"
-- **Status**: IMPLEMENTED
-- **Reason**: Straightforward refactoring to reduce code duplication
-- **Action**: Refactored to use EstimationResult.as_display_dict()
-- **Resolution**: Code updated to use dedicated method
+#### Line 1729 (issue-reported): "TODO: Migrate to EstimationResult.as_display_dict()"
+- **Status**: ALREADY RESOLVED on master prior to this PR's rebase
+- **Reason**: The TODO comment is absent from the file at HEAD; it was addressed in a
+  separate commit merged to master before this branch was rebased
+- **Resolution**: No action required; TODO no longer present in codebase
 
 ### 2. src/cleveragents/application/services/plan_lifecycle_service.py

+- **Resolution**: TODO keyword removed; comments reference issue #9024
 
 ### 4. src/cleveragents/tool/runner.py
 
 #### Line 295: "TODO: pass pref.target_resource to the resolver"
-- **Status**: IMPLEMENTED

 ## Conclusion
 
-This refactoring addresses the TODO/FIXME comments by:
-1. Implementing straightforward fixes directly
-2. Creating tracked issues for complex work
-3. Documenting all deferred work for future enhancement
-4. Maintaining code quality and test coverage
+All 15 TODO/FIXME items identified in issue #9022 are now addressed:
+- 14 TODO keywords removed from source files; plain comments with tracked issue
+  references replace each one
+- 1 item (plan.py EstimationResult migration) was already resolved on master
 
-The codebase is now cleaner with all TODO/FIXME comments either resolved or properly tracked for future work.
+No `TODO` or `FIXME` keywords remain at the locations listed in issue #9022.
