Implement XIC v2 control flow with IF, MATCH, LOOP operations

PHASE A: Safe predicate evaluator (glyphos/control/predicate.py)
- AST-based safe expression evaluation
- Supports comparisons, boolean ops, attribute access
- Helper function: dominant_contains()
- Protected against code injection attacks

PHASE B: XICContext queue helpers
- enqueue_chain(label) for FIFO chain scheduling
- pop_next_chain() to get next scheduled chain
- jump_to(label) for immediate destination changes

PHASE C: Control flow operations (xic_ops.py)
- op_IF: Conditional branching with optional else
- op_MATCH: Pattern matching against fused fields
- op_LOOP: Iterative execution with guardrails
- Added to OP_TABLE for operation dispatch

PHASE D: Execution loop enhancement (xic_vm.py)
- Chain queue scheduling with label matching
- Total steps tracking for guardrail enforcement
- max_total_steps limit across all operations
- Graceful execution stop on guardrail trigger

PHASE E: Comprehensive test suite (tests/test_control_flow.py)
- 14 unit tests covering all operations
- Predicate evaluator tests
- IF/MATCH/LOOP operation tests
- Queue helper and guardrail tests
- All tests passing (14/14)

PHASE F: Example programs
- demo_control_flow_if.gx.json: IF branching example
- demo_control_flow_loop.gx.json: LOOP iteration example

PHASE G: Complete documentation
- XIC_V2_CONTROL_FLOW_SUMMARY.md: Technical guide
- XIC_V2_QUICK_REFERENCE.md: Developer quick reference
- FedMart UI and integration documentation

Integration points:
- FedMart telemetry captures control flow steps
- UI dashboard displays control branching
- Symbolic pipeline predicate evaluation
- 100% backward compatible with XIC v1.5

Test results: 36/36 passing (14 control flow + 12 FedMart + 10 UI)
Status: Production ready
