feat(P1-002): migrate offline JSONL import/export to dedicated CLI

- Replace the MCP import_messages tool with standalone CLI commands:
  	iny-convmem-mcp --data-dir <path> --import <file>
  	iny-convmem-mcp --data-dir <path> --export <file>
- Add src/cli/{import,export,cli.h} and a CTest process test (tiny-convmem-mcp.cli)
  covering round-trip, manifest generation, overwrite/reject policies, and
  include_deleted export.
- Fix Debug heap corruption in 	iny_store_import() by deep-copying imported
  messages instead of taking ownership of caller-allocated records, which were
  later freed by the caller.
- Remove the now-redundant src/mcp/tools/import_messages.c and keep the tool
  registry at 7 MCP tools.
- Update docs/development-plan.md (P1-002 complete) and
  docs/implementation-status.md with CLI test coverage.
