feat(workflow): add disconnect edit operation

[christian-byrne]

Summary

• add comfy workflow disconnect <file> <node>.<input>
• emit and replay a first-class disconnect op sharing the concrete-input LWW register with connect
• support disconnect specs in atomic workflow batches and document the vocabulary amendment

Validation

• uv run pytest -q tests/comfy_cli/command/test_workflow_edit.py -k disconnect
• uv run pytest -q tests/comfy_cli/test_connect_lww.py tests/comfy_cli/test_op_vocabulary_contract.py
• uv run ruff check ...
• uv run ruff format --check ...

📝 Walkthrough

Walkthrough

The PR adds a batchable and replayable disconnect operation. The CLI removes an input connection, reports validation errors, and emits the operation. Replay applies LWW handling to concrete, promoted, and autogrow targets. Documentation and tests cover the behavior.

Changes

Workflow disconnect

Layer / File(s)	Summary
Disconnect operation contract comfy_cli/workflow_ops.py, docs/op-vocabulary-v1.md	The operation vocabulary and batch handling include disconnect. The primitive validates targets, rejects empty inputs, and emits a stamped operation.
Disconnect replay and conflict handling comfy_cli/workflow_ops.py, tests/comfy_cli/test_connect_lww.py	Replay applies disconnect with LWW handling for concrete, promoted, and autogrow targets. Winning operations remove links. Losing or invalid operations do nothing. Autogrow handling preserves grow_id identity and converges with connect.
Disconnect command and validation comfy_cli/command/workflow.py, comfy_cli/command/workflow_edit.py, tests/comfy_cli/command/test_workflow_edit.py	The workflow command invokes disconnect, parses target addresses, writes workflow and operation output, and reports errors for unconnected inputs. Tests cover link removal and identity preservation.

Priority: ⬇️ Low

Merge Risk: ⚪ Minimal · up to 42b14

The disconnect operation removes links while preserving dynamic-input identity and replay convergence; current coverage shows no merge-blocking risk remains.

In `@comfy_cli/workflow_ops.py`:
- Line 1101: Update disconnect handling in _apply_disconnect and apply_op to
preserve the dynamic slot’s grow/link identity and record its LWW tombstone even
when the input has not yet been materialized, then apply that tombstone when the
matching connect creates the slot. Add reversed-replay coverage for ordinary
autogrow inputs and widget-converted inputs such as KSampler.cfg.
