feat(joinir): Phase 49-3.2 merge_joinir_mir_blocks full implementation

Implement actual block merging for JoinIR Frontend mainline integration:

- Block ID remapping: Allocate new IDs from block_gen for all JoinIR blocks
- Value ID remapping: Allocate new IDs from next_value_id() for all values
- Instruction cloning: Clone all instructions with remapped IDs
- Return→Jump conversion: Convert Return terminators to Jump to exit block
- Control flow wiring: Jump from current block to JoinIR entry

Helper functions added:
- collect_values_in_block(): Collect all ValueIds in a block
- collect_values_in_instruction(): Collect all ValueIds in an instruction
- remap_instruction(): Remap ValueIds and BlockIds in an instruction

A/B tests (3 total):
- phase49_joinir_mainline_pipeline_smoke
- phase49_joinir_mainline_fallback_without_flag
- phase49_joinir_mainline_ab_comparison (Route A vs Route B)
